A Surprising Pivot for a Former Idol
Mark Lee, formerly of NCT and SM Entertainment, has hinted at an unexpected new musical direction: Kids-POP. According to a report by Koreaboo, the artist shared his plans during an episode of the Upper Room YouTube channel titled 'Mark Lee & Kids-POP', released on 9 October. The episode shows Mark spending time with two young children at a kids' cafe and later at a coin karaoke room, an experience that apparently inspired him to consider making music for a younger audience.
While the episode does not confirm a formal career shift, his comments suggest he is seriously contemplating a move into children's music.
The news comes after Mark's departure from NCT and SM Entertainment, a significant change for an artist who had been a prominent figure in one of K-pop's biggest acts. His potential pivot to Kids-POP raises questions about artistic reinvention, the children's music market, and how a former idol transitions into a new genre. This article examines what Mark said, the context of his career, and what Kids-POP could mean for him and the broader K-pop industry.
It is important to note that the source reporting is from Koreaboo, and the episode itself did not announce a specific release or label deal.
Mark Lee's Career and Departure from NCT
Mark Lee, known simply as Mark, is a Korean-Canadian singer who rose to fame as a member of NCT, the SM Entertainment boy group known for its rotational lineup and multiple sub-units. He was active in NCT 127, NCT Dream, and the supergroup SuperM, earning a reputation as a versatile rapper, singer, and dancer. His departure from SM Entertainment and NCT, reported earlier, marked the end of a significant chapter in his career.
Leaving a major agency like SM is a bold move, as it often means forfeiting the infrastructure and promotional power that come with a large label.
Since leaving, Mark has been exploring new creative avenues. The Upper Room episode is one such venture, showing him in a more relaxed, playful setting than the polished stages of K-pop. This shift towards independent content production aligns with a broader trend of artists using YouTube and other platforms to connect directly with audiences. For Mark, the episode serves as both entertainment and a testing ground for new ideas.
His interest in Kids-POP may be an extension of this exploratory phase, allowing him to experiment without the pressures of a traditional comeback. It also reflects a growing willingness amongst former idols to redefine their careers on their own terms.
Inside the Upper Room Episode
The episode, released on 9 October, documents Mark's visit to a kids' cafe, where he meets two children. According to Koreaboo, he quickly bonds with them, playing with toy cars and pretending to be a monster. The setting is deliberately informal, designed to foster natural interactions. Later, the group moves to a coin karaoke room, a popular pastime in South Korea where users pay per song. There, Mark performs his own track 'Too Much' at the children's request.
However, as the English lyrics progress, the children begin to lose interest, prompting Mark to laugh.
The children then choose their own songs, which Mark listens to attentively. This moment appears to be the catalyst for his revelation. He reportedly says that he wants to make songs like the ones the children selected, and that if he does, they must sing along. He thanks them for letting him hear such great songs and says he will return with music of his own, planning to make Kids-POP starting now. He explains that this is why they met that day.
After the day ends, Mark describes the experience as an inspiration day, noting that the children listen to music that is more mature than he expected. He says he thought it might be fun to write lyrics more directly from a child's perspective, and that a variety of things could come out of it.
The Significance of the Children's Reaction
The children's loss of interest in 'Too Much' is a revealing moment. While the song is one of Mark's own, its English lyrics and likely complex structure did not hold the attention of a young audience. This is not a criticism of the track, but rather an illustration of how children's music preferences differ from those of adults or older fans. Children often gravitate towards simple, repetitive, and participatory songs with clear melodies and hooks.
They enjoy music that invites them to sing along, dance, or respond physically. Mark's observation that the kids listen to more mature music than he expected is interesting; it suggests that even young children have sophisticated tastes, but their engagement depends on accessibility.
Mark's comment about writing lyrics from a child's perspective is key. It indicates that he is thinking about authenticity and empathy, rather than simply dumbing down his existing style. Kids-POP, as he envisions it, would require a different songwriting approach: shorter sentences, relatable themes, and opportunities for call-and-response. The fact that the children chose their own songs and Mark listened attentively shows a willingness to learn from his audience. This collaborative spirit could serve him well if he pursues this genre.
It also highlights a potential gap in the market for music that respects children's intelligence while being tailored to their developmental stage. Such an approach could differentiate him from more generic children's entertainment.
What Exactly Is Kids-POP?
Kids-POP is not a widely established term, but it can be understood as pop music specifically created for children. It sits at the intersection of entertainment and education, often featuring catchy melodies, simple lyrics, and themes relevant to young listeners. In South Korea, children's music has traditionally been dominated by animated soundtracks, nursery rhymes, and educational songs from programmes like Pororo or Pinkfong. However, a dedicated Kids-POP genre, branded and marketed like K-pop, could represent a new approach.
It would borrow the production values, choreography, and visual polish of K-pop but adapt them for a younger demographic.
The global children's music market is substantial, driven by streaming, YouTube, and live events. Parents actively seek content that is safe, engaging, and ideally educational. If Mark Lee enters this space, he would be competing with established children's brands and YouTube channels, but he would also bring a built-in fanbase and name recognition. His background in K-pop could lend a certain credibility and appeal, especially if he incorporates high-quality production and performance elements.
However, success would depend on understanding the needs of children and their caregivers, not just repackaging idol music. The genre also requires a different lyrical vocabulary, one that avoids innuendo and focuses on curiosity, friendship, and everyday wonders.
Marketing and Distribution Considerations
Releasing Kids-POP would require a different marketing strategy than a typical K-pop comeback. YouTube would likely be a primary platform, given its dominance in children's content consumption. The Upper Room channel itself could serve as a launchpad, building on the audience from the episode. Music videos, lyric videos, and interactive content would need to be designed for young viewers, with bright colours, simple animations, and clear vocals. Streaming services have dedicated children's sections, but discovery often happens through algorithms and parental recommendations.
Therefore, Mark would need to ensure his content is easily searchable and age-appropriate.
Live performances would also look different. Instead of concert halls, Kids-POP artists might perform at family festivals, shopping centres, or dedicated kids' theatres. Merchandise would target children and parents, from plush toys to sing-along books. There are also ethical considerations: working with children requires safeguards, and marketing to minors is heavily regulated in many countries. Mark would need to navigate these issues carefully. On the plus side, children's music can have a long shelf life, with songs reused across generations.
If he creates a hit, it could become a lasting part of his legacy. The financial model may rely more on licensing and live appearances than on album sales, which is a shift from traditional K-pop economics.
Artistic Transition and Authenticity
Moving from idol pop to Kids-POP is an unusual transition. Mark Lee has spent years performing for predominantly teenage and adult audiences, with music that often explores themes of love, ambition, and youth. Kids-POP would demand a different persona: more playful, more direct, and less reliant on irony or innuendo. This could be seen as a risk, as some existing fans might struggle to connect with the new direction.
However, it could also be liberating, allowing Mark to shed the pressures of the idol system and create something genuinely new. It is worth noting that many artists have successfully reinvented themselves by targeting younger audiences, though few have done so as explicitly as Mark is suggesting.
Authenticity will be crucial. Children are perceptive and can tell when something is condescending or insincere. If Mark approaches Kids-POP as a genuine creative challenge, rather than a gimmick, he may win over both children and their parents. His comments in the episode suggest that he is approaching it with curiosity and respect. He did not claim to have all the answers; instead, he described the day as an inspiration and expressed a desire to learn. That humility could be his greatest asset.
It also aligns with a broader cultural shift towards artists exploring diverse creative paths beyond the traditional idol model. For fans, watching this evolution may be as rewarding as any comeback.
The Broader K-pop Context
Mark Lee's potential move into Kids-POP is not happening in a vacuum. The Korean music industry has long recognised the value of younger audiences. Agencies have launched junior groups, produced animated series, and released educational songs. However, these efforts are often tied to specific brands or television programmes. A standalone Kids-POP artist with a K-pop pedigree would be a relatively novel concept. It reflects the increasing fragmentation of the music market, where artists can target niche audiences directly, bypassing traditional gatekeepers.
This trend has been accelerated by social media and streaming, which allow creators to build communities without a major label.
The rise of kids' cafes and family entertainment spaces in South Korea, like the one featured in the episode, points to a growing demand for child-friendly cultural experiences. Parents are willing to spend on activities and content that engage their children in a safe environment. If Mark can tap into this trend, he could build a sustainable career. Moreover, his English fluency and international background might allow him to reach global audiences, not just Korean ones.
This cross-cultural potential is significant, as children's music travels well across borders when language is kept simple. It could also position him as a bridge between K-pop and Western children's entertainment, a space that remains relatively unexplored.
Challenges and Opportunities Ahead
The biggest challenge is consistency. Kids-POP requires a steady stream of new content to keep young audiences engaged. Unlike a single album, children's music often involves regular releases, accompanying videos, and interactive elements. Mark would need a team that understands child development, education, and entertainment. He would also need to decide whether to release music under his own name or create a separate brand. The latter might allow him more freedom but could also dilute his personal connection with the audience.
Additionally, he would need to consider how to handle live performances, as young children have shorter attention spans and different safety requirements.
Opportunities include collaborations with children's brands, educational institutions, and streaming platforms. A Kids-POP song could be licensed for a cartoon or a toy commercial, providing both income and exposure. Live shows could become family events, with parents happily paying for tickets. There is also the potential for positive social impact, as quality children's music can support language learning and emotional development. However, Mark must be careful not to overcommercialise; trust is hard to earn and easy to lose.
If he prioritises artistic integrity, he could become a pioneer in this space. The rewards, both creative and financial, could be substantial if he gets the balance right.
What Happens Next?
At this stage, Mark Lee's Kids-POP plan is more of an intention than a confirmed project. The episode did not announce a release date, a label, or a specific format. It simply showed him expressing a desire to explore this direction. Fans and industry observers should treat it as a possibility, not a certainty. Mark may release a Kids-POP single, or he may incorporate elements of it into his broader solo work.
He may also decide that the idea is better suited to a side project. The lack of confirmation is important; it means he has room to experiment without pressure. It also protects him from overpromising before he has a clear plan.
Regardless of the outcome, the episode offers a fascinating glimpse into Mark's creative process. It shows him stepping outside his comfort zone, engaging with a new audience, and finding inspiration in unexpected places. If he does pursue Kids-POP, he will be venturing into largely uncharted territory for a former K-pop idol. That alone makes it a story worth watching. For now, we can only wait to see what music he returns with.
As he told the children, he will come back with music of his own. Whether that music is for kids, for adults, or for everyone, it will be shaped by the lessons he learned on that inspiration day. The K-pop world will be watching closely.
