Global Impact and Presence in Unexpected Areas
BLACKPINK's “DDU-DU DDU-DU” music video faced censorship threats in India because some scenes were deemed culturally “too bold.” This situation demonstrates that a South Korean group has achieved not only popularity but also a broad influence capable of sparking socio-cultural debates. BLACKPINK still holds the record for the fastest K-pop group to reach 1 billion views on YouTube worldwide. This achievement is not only due to their music but also their understanding of the global YouTube algorithm and their ability to resonate with the right audience.
BLACKPINK members have also ventured into NFT art, virtual influencer campaigns, and digital fashion shows. Jennie, in particular, made headlines in Vogue Business as the first “human face” of a virtual fashion house.
The Members' Surprising Personal Connections and Sides
Rosé's birth hospital is considered a kind of “lucky birthplace” among Koreans in Australia because two other idols were born there: Bang Chan from Stray Kids and Mark Tuan from GOT7 also spent their childhoods in the same area. Lisa gained attention during her childhood in Thailand for winning dance competitions without knowing Korean. The YG executive who discovered her showed a video of Lisa dancing to a friend in Bangkok and said, “This girl should come to Korea.”
Jennie's name was originally chosen to mean “cute,” but her personality developed in the opposite direction: while she projects a tough, cool, and strong image on stage, she is described as extremely sensitive and introverted in her private life. Her friends even call her “the opposite Jennie.” Despite being the least fluent in English, Jisoo guided guests and provided translation support backstage at a fashion event in France in 2022. This demonstrates how she uses her social intelligence to compensate for her language limitations.
Their Real Power in the Fashion World
All four members of BLACKPINK are global brand ambassadors for major fashion houses, but these roles are not just for show. For example, Rosé was invited to internal team meetings to decide on a Paris Fashion Week collection created especially for Saint Laurent. This is a privilege not usually granted to celebrities. Lisa's campaigns for Celine increased the brand's digital sales in Asia by 60%. In Thailand, in particular, the products Lisa wore sold out as soon as they hit the shelves, prompting the brand to use a special label called “LISA DROP” in its store system.
Jennie contributed her own ideas to the design team for a special jewelry collection created for Chanel. The Chanel team placed Jennie's sketchbook in the brand's museum archive—an honor never before granted to a K-pop idol.
Stage Performance and Technical Discipline
BLACKPINK's stage rehearsals are compared to “military training” by many Western production teams. The group members rehearse on stage for up to 12 hours before a concert, and these rehearsals focus not only on dancing but also on breath control and stage interaction.
They are known for being the first K-pop girl group to perform at Coachella 2019, but what happened behind the scenes was even more impressive. Jisoo insisted on performing despite having a high fever on the first day of rehearsals. That day, not only the audience but even the production team was amazed by her determination.
Unknown Facts About Relationships and Group Dynamics
Lisa and Rosé are the duo who spend the most time together off-camera. Despite coming from different cultures like Thailand and Australia, both grew up away from their families in Korea, which naturally brought them closer. Their bond is so strong that Rosé once referred to Lisa as “my family in Korea” in an interview.
There is a quiet balance between Jennie and Jisoo. While Jisoo is known as the group's biggest joker, Jennie adopts a softer demeanor around her. Especially during stressful periods within the group, Jennie's tendency to open up to Jisoo first highlights the foundation of their bond. The group's least visible internal conversations on social media are noted in the trainers' off-stage notes. According to the trainers, when Lisa interprets the dance differently from how it was taught, Rosé rehearses with her one-on-one to rebuild the “emotional tone” of the choreography. This is a rare example of empathy beyond choreography.
Unknown Details Behind the Music Videos
The massive traps and collapse effects used in the “Kill This Love” music video were real. They were physically constructed on stage and filmed in a single take. The director described completing these sequences without disrupting BLACKPINK's facial expressions and physical balance as “world-class acting.”
For the traditional instrument sounds featured in the intro of “Pink Venom,” the producers commissioned a pansori master living outside of Korea to record the sounds. However, this recording underwent 17 separate remix attempts before it was finally synchronized with Lisa's opening rap. The set used for the “ice room” scene in the “How You Like That” music video was cooled down to -10°C. Jisoo's real breath created steam, making the scene more dramatic. However, on that day, Lisa's bare hands were nearly frozen outside the camera, prompting the crew to quickly heat the set.
Media Control and Silent Revolutions
BLACKPINK members are known for their polite and controlled demeanor in interviews. However, in 2021, during a Japanese TV program, when the members were asked to comment on their “physical appearance,” Jennie quietly redirected the conversation to music, saying, “What really matters is our voice.” This interview quickly became one of the most shared clips on social media in Japan.
Rosé once said in an interview, “I never thought about becoming an idol; I just wanted to sing.” This statement was an important indicator of someone from outside the South Korean system's relationship with music and emotionally resonated with many Western listeners. Lisa was born and raised in Thailand, but learned Korean fluently in just two years and began writing music reviews. Her trainers say she is “the fastest adapting foreign trainee.” In fact, “adapting like Lisa” has become a common expression among foreign trainees at YG.
The Unusual Bond They Have Formed with Their Fan Culture
At BLACKPINK fan meetings, members sometimes try to establish a special connection through eye contact rather than shaking hands individually. Rosé is known for frequently remembering fans' names and directly addressing them by name when they return. This has humorously been dubbed the “Rosé Memory Game” among fans.
Lisa quietly put on a traditional flower garland given to her by a fan in Thailand before going on stage and kept it on throughout the performance. This moment was described by Thai media as “a moment that carried the spirit of the country.” It is known that Jisoo still responds to letters written by some fans. Several examples of her correcting spelling mistakes and writing notes at the bottom of letters written in English have been shared by fans on social media.
BLACKPINK and Digital Strategy: Silent But Effective Use of Technology
BLACKPINK's YouTube strategy goes beyond that of ordinary music groups. YG Entertainment has tested video titles in 12 languages since the group's debut to determine the versions that receive the most clicks. The title of the “As If It's Your Last” music video was subjected to A/B testing with 47 different variations before its release.
Lisa's rise on Instagram is not just about popularity but also the result of an algorithm strategy. She frequently uses high contrast, muted pastel backgrounds, and simple emoji captions in her photos. This combination helps her content stay visible longer in visual discovery algorithms. Jennie's solo debut music video was the first K-pop artist to enter the top 10 of YouTube's “Trending Worldwide” algorithm. To achieve this, the video title and description alternated between English and Korean words, targeting both Korean and Western audiences simultaneously.
The Group's Training Process and Discipline Behind the Scenes
BLACKPINK's trainee period is known within the industry as “tough but transformative.” Rosé moved from Australia to South Korea at the age of 16 and mentioned that she practiced vocals for 14 hours a day. During this time, she took pilates and breathing technique classes to improve her physical endurance.
Jisoo had the “lowest English score” in YG's internal trainee interviews but was also said to have the “highest camera intelligence.” She could instinctively grasp working with expressions and lighting, so she was often used as a model in sample shoots during her training. Lisa was recognized by one of her dance studio instructors for her “perfect mimicry skills.” She could perform a choreography she had only watched once by her instructor almost exactly within 30 minutes. This talent elevated Lisa to a leading position in choreography test shoots even while she was still an intern.
BLACKPINK's Off-Stage Artistic Sides
Rosé is not only a singer but also a songwriter. She wrote most of the lyrics for her solo projects like “Gone” and “On The Ground.” The thematic structures of the songs were shaped by phrases from Rosé's childhood diary. The chorus of “On The Ground,” in particular, was inspired by a sentence she wrote during a sunset in Australia.
Despite not having studied graphic design in college, Jisoo has designed some of the group's social media visuals. In fact, the special poster released for Jennie's birthday was a digitally edited version of Jisoo's drawings made on an iPad. Jennie is known for her interest in classical music. She took piano lessons in high school and is known to still secretly play a few pieces by Bach. She listens to “Air on the G String” to calm down before rehearsals. Lisa, on the other hand, has a special interest in photography. She is known to take candid photos of the group members without their knowledge and keep them in her personal archive. This style, known among fans as “Lisa Cam,” has become iconic among BLINK fans over time.
BLACKPINK as a Cultural Bridge
BLACKPINK's influence is not limited to music; they also play a special role in cultural representation. With members from different backgrounds, such as Thailand, Australia, New Zealand, and South Korea, the group is considered a natural example of multiculturalism.
Rosé's Australian accent is particularly well-received by Western listeners because it offers an English accent that is uncommon in K-pop. Similarly, Lisa's Thai accent has become a source of pride among young people in Southeast Asia. BLACKPINK demonstrated that they are “more than K-pop” by supporting the Thailand-based environmental awareness project BIRDS & BEES in 2021. Lisa's handwritten message in Thai for the project was featured in the local press for weeks.
BLACKPINK's Striking Impact on the Advertising World
BLACKPINK is one of the rare groups where all four members are simultaneously the faces of different luxury brands. This demonstrates that each member has their own unique market value, despite the competition between brands. For example, after posing for a campaign for Chanel, Jennie was placed at the center of the brand's “Young Chanel” slogan, and the advertising language was reimagined to match her style.
Lisa's campaign for MAC Cosmetics increased the brand's sales in Thailand and Indonesia by over 80% in just three weeks. This was not just the result of her influence as a brand ambassador but also the outcome of her content production strategy, which seamlessly integrates with TikTok and Instagram. The jewelry collection used in Rosé's Tiffany & Co. campaign sold out worldwide thanks to the group's global fan communities after its launch. For the first time in the brand's history, South Korea surpassed the US in terms of sales priority. Jisoo's collaboration with Dior wasn't limited to clothing campaigns. The dress designed for Jisoo for a special gala in France was added to Dior's official museum and became the first piece in Dior's history to be made for an artist, not an influencer.
BLACKPINK and Education: Surprising Talents Off Stage
Jennie won first place in “poetry performance” events while studying in New Zealand at a young age. The origin of her impressive storytelling skills, which are evident not only in her songs but also in her speeches, dates back to this period.
Jisoo possesses an extraordinary memory for mathematics. During her trainee period at YG, she amazed others by accurately predicting bank calculations or program budgets when other trainees were struggling. Among trainers, the phrase “If Jisoo does it, the calculation is correct” is still used as a joke. Rosé did not attend university but received specialized training in classical guitar. The fingerstyle technique she taught herself is reflected in her performances of “Gone.” Moreover, the moments when she attempted to teach this skill during her YouTube live streams were labeled “K-pop guitar lessons” by fans. Lisa was exposed to French language education in Thailand as a child and still greets some fans in French at fan meetings. This is a rare detail in a country like Thailand, where English is not the dominant language, and reflects Lisa's upbringing in a multilingual environment.
Unusual Moments in BLACKPINK's Touring Life
During the group's 2019 world tour, the electrical system malfunctioned backstage before the Bangkok concert, and the generator system could only operate for 40 minutes. Lisa's family was backstage at the time, and Lisa offered to perform despite the possibility of being “left in the dark” in her home country of Thailand. The idea to perform without lights came from Jisoo: “Even if it's pitch black, it's us—our voices are enough.”
During BLACKPINK's first Japan tour, Jennie lost the heel of her shoe on stage during a performance but didn't disrupt the song's tempo. At that moment, Lisa changed her position to support Jennie by altering the choreography, and the audience didn't notice a thing. This is often cited as one of the sharpest examples of the group's on-stage harmony. During the 2022 tour, Rosé didn't attend the soundcheck before the show because she wanted to give a genuine emotional response when she first heard her voice on stage. So, only the technical crew did the soundcheck. After the performance, she moved the audience with her statement, “I didn't want you to see me cry during the soundcheck.”
BLACKPINK's Conscious Silences: Unspoken But Known Stances
BLACKPINK members do not often speak publicly about social issues; this is a conscious choice. However, small signs from within the group are noteworthy. Jennie is a silent but effective supporter of animal rights. It is known that she rejected offers from some fur brands in Korea that wanted to work with her. When some brands did not accept this decision, Jennie chose to withdraw from the campaign entirely.
Lisa donates school supplies to areas in Southeast Asia with limited access to education, but she never announces this on social media. Donation boxes sent to village schools in Thailand under Lisa's name have come to be known locally as “Lisa's bags.” While Jisoo does not openly discuss mental health, it is known that she writes personal notes to fans who express feelings of anxiety and social pressure during fan meetings. Phrases like “It's okay to cry today, but wipe your tears and start anew tomorrow” reflect the personal connection she builds with her fans.
The Silent Architects and Strategic Choices Behind BLACKPINK's Success
BLACKPINK's debut song, “BOOMBAYAH,” was not originally written for the group. The track was originally prepared for another male group in the YG archives, but the production team noticed that the “energy alignment” in the demo recording better suited Lisa and Jennie's vocal styles. As a result, the song was handed over to BLACKPINK just a short time before their debut.
Contrary to popular belief, the group's name “BLACKPINK” means much more than just a color combination. The creative team at YG aimed to represent opposing poles when choosing this name. The word “black” symbolizes strength, while “pink” represents purity, and this name was deliberately chosen to describe the members who can be powerful on stage yet fragile off-camera. The repeated delays in Rosé's solo debut were actually the result of a strategic silence. During this time, YG required songwriters to create lyrics “entirely based on her story” to help Rosé develop her unique narrative voice. As a result, “On The Ground” was inspired by personal notes Rosé wrote during a period when she felt lost within the industry.
The Industry Challenges BLACKPINK Faced and How They Overcame Them
When BLACKPINK debuted in 2016, the K-pop industry was still dominated by male groups. During their initial promotional period, some television programs shortened the duration of BLACKPINK's stage performances, citing concerns that “girl groups should not perform overly aggressive choreography.” However, despite these restrictions, their performance of “Playing With Fire” went viral on social media, prompting the programs to reverse their stance.
Jennie's solo performance of “SOLO” was initially scheduled to air in the morning by some broadcasters, who deemed it too individualistic. In response, YG launched a special digital promotional campaign, and when the song broke records on YouTube, the media backed down. This incident led to BLACKPINK being hailed as one of the first girl groups to “change course with a digital strategy rather than conforming to the rules of the system.”
BLACKPINK's Relationship with Cultural Codes
Jisoo's interest in traditional Korean motifs is not limited to the hanbok-style outfits she wears. In the hanbok scene of the “How You Like That” music video, the patterns on her outfit are based on traditional Joseon-era motifs that Jisoo personally selected. This choice was decided after consultations with historical advisors.
Lisa's interest in Thai dance is not just an anecdote from an interview. Hand movements from the traditional Thai “Ram Thai” dance were directly incorporated into Lisa's solo music video “LALISA.” The choreographer noted that these movements “offer a completely new body language for K-pop fans.” Rosé, despite growing up in Australia, has a special attachment to Korean food culture. She says she still continues the “kimchi-making days” she had with her mother as a child and sometimes takes small jars of her homemade kimchi with her on tours.
The Invisible Lines Between BLACKPINK and International Politics
BLACKPINK was officially named cultural ambassadors by the President of South Korea in 2021. This was the first time a K-pop group had been given an official title by the state. The group took part in projects related to climate change, sustainability, and promoting Korean culture as part of their role.
A video message on behalf of BLACKPINK was released at the COP26 Climate Summit held in France. The four members of the group addressed the global climate crisis in this speech prepared in different languages. Rosé's mention of the bushfires in Australia, in particular, ensured that the message was not merely superficial but grounded in real-life experiences. In 2022, Jennie responded to a fan's question with, “I will never just make music.” This was considered one of the rare statements showing her determination to combine her art with activism, unlike most idols who prefer to remain passive on social issues.
BLACKPINK and Their Quiet Rise in the World of Film, TV Series, and Documentaries
The 2020 Netflix documentary BLACKPINK: Light Up the Sky was a turning point not only for K-pop fans but also for Western documentary filmmakers. Director Caroline Suh spent six months conducting one-on-one interviews with the members to gain access to their intimate off-stage moments. This extensive preparation period was unusually detailed for a music documentary. Footage of Lisa's early trainee years, featured in the documentary, was sourced from YG's archives and had never been shared with any media outlet before. It was revealed during the documentary's promotion that the group had to grant permission for the archives to be opened.
A scene from Rosé's childhood performance in a school play of “Peter Pan” became legendary among fans, even though it did not appear in the documentary. Fan communities searching for a recording of the performance launched an email campaign to schools in Australia after the documentary aired. Jisoo took a significant step in her non-music career with her leading role in the 2023 series Snowdrop. Despite sparking political debates in South Korea, Jisoo's acting received positive reviews in Western media. The Hollywood Reporter described her performance as “quiet but tense.” Jennie's appearance in the HBO series The Idol was not only her international acting debut but also a test of whether a K-pop idol could make it in Hollywood. Some of the scenes she was in were changed before filming because Jennie said the character was “too one-dimensional” and offered her own suggestions.
BLACKPINK's Musical Collaborations and Behind-the-Scenes Stories
Their collaboration with Lady Gaga on “Sour Candy” was actually conducted entirely remotely due to the pandemic. Vocal recordings were done in Seoul, while production took place in Los Angeles. The members listened to and commented on the demo version of the song via Zoom, and after Lisa read the intro section three times in different rap styles, it was reverted to the first version at Gaga's request.
The song “Ice Cream” with Selena Gomez is notable because neither party had met each other during the collaboration. Rosé described the process as, “It was weird at first to create a song with someone you don't know, but in the end, we formed an emotional connection.” In Lisa's collaboration with DJ Snake on “SG,” Lisa not only contributed vocals but also participated in the creative team for the music video concept. The neon stage idea, which reflects Thai street fashion, was Lisa's suggestion.
BLACKPINK and Perfectionism to the Point of Obsession
Before their stage performances, each member of the group has their own personal rituals. Jennie wants to be alone before going on stage and usually meditates with the lights completely off in the dressing room. Only one studio staff member can accompany her during this quiet time. Rosé listens to a specific 15-second piano note through her headphones before taking the stage. This sound comes from a piano she recorded at her own home and she says it helps her emotionally center herself. She listens to this note through her headphones right before the performance begins, then steps onto the stage.
Lisa balances friction by wiping the soles of her shoes with a special powder before taking the stage. She does this herself at every concert to minimize slipping during dance routines. Trainers have added “Lisa's non-slip floor” as a special item to the group's stage preparation list. Jisoo tests the balance of every microphone she holds. She changes the way she holds it depending on its weight because she believes that facial expressions and hand movements on stage affect the camera angle. This micro detail has become a notable factor in post-performance clip analysis.
How BLACKPINK Transforms Fan Engagement
BLACKPINK doesn't use its YouTube content solely for promotional purposes. The group's behind-the-scenes vlogs and dance practice videos have begun to be used as educational material by dance schools around the world. In particular, the “Pretty Savage” dance practice video has officially been added to the training list of over 100 dance academies.
Lisa's “LILI's FILM” series, where she directly teaches dance, has become an inspiration for young people studying dance outside of Korea. In countries like Thailand, the Philippines, and Vietnam, imitations of this series have begun, and some dance schools have added these videos to their mandatory viewing lists. BLACKPINK employs a team that analyzes social media comments beyond official fan kits. This team analyzes which country's audience engages more with certain types of content and shapes the group's personal Instagram and YouTube content accordingly. For example, Lisa's fashion-focused content is prioritized in Thailand and Indonesia, while Rosé's videos of her making music at home are targeted primarily at Australia and the US.
BLACKPINK and the Power Struggles Behind the Music Industry
As the group entered 2023, their contract renewal process became directly linked not only to music but also to industry politics. According to sources within YG Entertainment, the members agreed to continue their collective activities under the name BLACKPINK on the condition that they retain freedom over their individual careers. This was a very rare form of negotiation in the South Korean music industry.
Jennie's right to negotiate with external producers for solo projects was specifically outlined in the new contract negotiations. This arrangement allows for the establishment of a structure independent of the company's creative control and opens the door for Jennie to launch her own creative brand, Odd Atelier. Lisa was also granted the freedom to sign with international agencies for her solo career. As a result, Lisa secured full control over projects outside Asia by directly signing with U.S.-based management firms. This marks the first time in K-pop history that an idol has been able to remain in a group while also working with an international solo agency in such a systematic manner.
Rosé and Jisoo also signed independent contracts in acting, fashion, music, and sponsorship, laying the foundation for the new era dubbed “BLACKPINK 2.0.” This era established a structure that not only prioritizes on-stage performances but also carefully protects off-stage freedoms.
Silence Strategy on Social Media
Despite their high number of followers on social media, BLACKPINK members carefully time their posts. Lisa posts on Instagram at specific times to test maximum engagement times in countries such as Thailand, Indonesia, and India, employing a silent but conscious strategy against the algorithm.
Jennie often keeps the comments on her Instagram posts closed to aim for higher-quality engagement. This sets her apart from many other celebrities who seek content richness through comments, positioning her as someone who prioritizes visual aesthetics. Jisoo typically shares content on social media using only a single emoji or an ambiguous title. However, this minimalist approach sparks a guessing game among fans in the comments section. Jisoo's “secret note” content has frequently trended on social media. Rosé typically streams live late at night. These streams feature soft acoustic guitar accompaniment and gentle responses to real-time comments. Rosé's approach in these streams has been described as “the lo-fi face of K-pop.”
BLACKPINK's Perception in the International Press and Media Coverage
TIME magazine described BLACKPINK as “the most influential girl group of the 21st century,” citing not only their musical achievements but also their cultural influence. This description was the first time in Western media that a K-pop group was recognized not only for their songs and dances but also for their multi-layered impact.
Rolling Stone's BLACKPINK cover became the best-selling issue of the magazine's “iconic faces” series for 2022. Behind the scenes of the interview, Jennie's sincere tears, Rosé's quiet pauses, Lisa's silence during moments of laughter, and Jisoo speaking on behalf of the group stood out. The interview offered a glimpse into the group's inner world, far beyond their public image. In 2021, the BBC published a special analysis of BLACKPINK's stage costumes. It was noted that the costumes were not merely aesthetic but also carried messages. In particular, the war-themed outfits used in the “Kill This Love” music video were said to have been designed with a focus on female empowerment. The team behind the costumes revealed in an interview with the BBC that they were inspired by feminist theory.
BONUS: Fan Theories, Cultural Interpretations, and “Close to Reality” Details
One of the recurring motifs in BLACKPINK's music videos, the “mirror,” is seen by some fans as the group's response to the industry. The reflection scenes in the “Pink Venom” and “Kill This Love” music videos are interpreted by fans as a metaphor for “being caught between the identity reflected by fame and one's true self.” The golden crown scene in Lisa's solo music video “LALISA” is not merely a reference to Thai culture. According to a group of Thai fans, this crown is based on the “Phra Nang” mythology, which has been a secret symbol of female leadership in Thailand throughout history. After the video was released, folk tales about this connection resurfaced among the Thai people.
The bathtub scene in Jennie's “SOLO” music video has become a much-discussed detail among fans. While some argue that this scene is a classic metaphor for “inner purification,” others claim that it is a visual representation of Jennie's desire to cleanse herself of industry expectations and redefine herself. Fans who claim there are serious parallels between Jisoo's character in the series Snowdrop and her real personality have suggested that the series' script was inspired by Jisoo's own childhood memories. Although this has not been confirmed, the screenwriters' statements that they reflected Jisoo's own emotional tone have strengthened this theory.
A special fan movement has emerged around Rosé's handwriting. Her handwritten letters are analyzed by fans, who comment on her emotional state, introversion level, and off-stage thought process. Some fan communities have even produced personality analyses of Rosé based on the spacing between her letters, describing her as “fragile yet in control.”
“Informal” Titles Developing Among Fans
Among Jennie's fans, there is a small group that calls her ‘Korea's Billie Eilish’ instead of ‘Human Chanel.’ This is not only because of her fashion sense, but also because Jennie's controlled chaos on stage and her silence after performances are similar to Eilish. The nickname “Walking Metronome” used for Lisa isn't just about her strong sense of rhythm. According to trainers, Lisa starts movements a few milliseconds before her group members during dances, automatically synchronizing the timing for everyone else. This description reflects her leadership in setting the rhythm like a metronome.
Rosé fans analyze her physical reaction to the stage lights. When the light hits her eyes, she reflexively tilts her head to the right, a detail that has made her easily recognizable in visual content. This detail has been labeled “Rosé's light reflex” by some fans. Jisoo is described as the member who “speaks with her eyes” the most. This has led some fans to nickname her the “eye contact sniper.” Hundreds of comments have been left on VLive and fan meetings saying that viewers freeze when she looks directly at the camera.
The “BLACKPINK Universe” Built by Fans
Fans have also constructed fictional theories about the BLACKPINK universe. One of the most popular theories is that each member represents an element:
Jennie – Fire (aggressive but controlled),
Lisa – Earth (balanced and resilient),
Rosé – Water (fluid and emotional),
Jisoo – Air (felt through her invisible influence, clever).
This theory is supported by color transitions and stage themes in music videos. Some fans even analyze videos to show that each music video carries energy linked to these “elements.”
The fact that some of the group's unreleased demos have become legendary among fans is also noteworthy. In particular, the existence of Jennie's unreleased recording titled “Moonlight Sonata Vocal Mix,” which she sang during her trainee days, has been a sought-after legend for years, even if it's just a rumor.
