Lee Soo-man's A2O Entertainment enters the debut race
After leaving the agency he founded, SM Entertainment's Lee Soo-man has been building a new operation. A2O Entertainment has already issued what The Bias List describes as loosey singles from various artists aimed at global markets. Now the company is preparing a double debut: A2O Lite and A2O Soul, female and male groups that appear to share a universe in the mould of SM's NCT.
The first proper look at A2O Soul comes in the form of 'Superstar', a track The Bias List reviewed on 12 October 2026 and considers a pre-release.
That timing matters because Lee Soo-man's post-SM moves have been watched closely across the industry. A pre-release from a brand-new boy group under his new label is not just another song review; it is an early signal of how the next chapter of his career might sound. The Bias List's verdict, an 8.75 grade, places the track in promising territory without declaring it a masterpiece.
A2O Soul and the NCT-style universe
The Bias List frames A2O Lite and A2O Soul as counterparts, with A2O Soul as the male group under the A2O umbrella. The review notes that the two acts seem to inhabit an NCT-style universe, a structure that will be familiar to anyone who followed Lee Soo-man's previous company.
That comparison is the reviewer's interpretation, not a confirmed blueprint, but it gives readers a useful reference point for what A2O might be attempting: multiple units, shared branding and a long-term rollout rather than a single standalone act.
A2O Soul reportedly has quite a few members, though The Bias List does not list them. The group's size and the pre-release strategy suggest a gradual introduction rather than a conventional debut splash. For listeners, that means the usual questions about line distribution, group identity and musical direction are still open. 'Superstar' is one early answer, not the final word.
What 'Superstar' sounds like, according to the review
The Bias List describes 'Superstar' as sleek and smooth rather than overbearing. The review says it is not completely unlike something from RIIZE, but credits its dynamic arrangement to oversight from legendary producer Yoo Young-Jin. According to the review, Yoo ensures every vocal is smooth and buttressed by enough harmony and interplay to stand out. The track is anchored by a bright synthline, which The Bias List says gives it a celestial texture that feels stately and grabs the ear immediately.
Crucially, the review highlights that this is an entirely vocal-focused song. There is no shouting, no talking and no chest-puffing, according to The Bias List. Instead, a series of strong voices build on each other to accentuate the track's charm. The reviewer calls it nothing experimental, yet finds its sheer existence in 2026 K-pop surprising. That tension, between a familiar synth-pop palette and a noticeably vocal-first delivery, is the heart of the review's positive case.
Yoo Young-Jin's production and the vocal-first choice
The involvement of Yoo Young-Jin is one of the few concrete production details in the source. The Bias List presents his oversight as the reason the vocals feel smooth and well-supported, with harmonies that do not overwhelm the melody. In an era when many K-pop releases lean on genre-blending, heavy effects or rap-centric structures, a pre-release that foregrounds singing is a deliberate choice. The review treats that choice as a strength, not a limitation.
For readers trying to place 'Superstar', the comparison to RIIZE is useful but not absolute. The Bias List's description suggests a polished, mid-tempo synth-pop track with an emphasis on vocal layering rather than a hard-hitting dance break or a dramatic tonal shift. That places it in a lineage of SM-adjacent sounds without claiming it is identical. The reviewer's grade of B+ reflects strong hooks and longevity scores alongside slightly lower production marks, a nuanced rather than uncritical assessment.
A pre-release strategy: what it signals
Calling 'Superstar' a pre-release matters. The Bias List says it is considered a pre-release 'from what I can tell', a phrase that signals the reviewer's own uncertainty rather than an official label statement. If that framing holds, the track functions as a calling card: enough to introduce A2O Soul's vocal identity without committing to a full debut campaign. It lets the group test audience response while keeping the main event, presumably a formal debut, in reserve.
Pre-releases have become a common way for new acts to build familiarity before the pressure of a full launch. For A2O Soul, the approach also fits the wider A2O universe, where A2O Lite and A2O Soul are being positioned as parallel projects. The Bias List does not detail what comes next, so readers should treat the pre-release status as a reported description rather than a confirmed rollout plan. What is clear is that 'Superstar' is being presented as an introduction, not a conclusion.
Listener split: the comment section
The Bias List's comment section shows that 'Superstar' has already divided early listeners. One commenter calls it 'pretty generic, like if I asked AI to generate me a synthpop song', rating it an 8 out of 10 while still describing it as fine. Another commenter takes the opposite view, saying they have not enjoyed a synthpop song this much in years, especially the vocals, and giving it a 9 for the vocals and hook alone.
They describe it as a song they could play from morning until night without tiring of it.
Those reactions are worth noting because they capture a real fault line in K-pop fandom: polish can read as either classy or anonymous, and vocal-forward production can feel either refreshing or safe. The Bias List's own review sits between those poles, praising the execution while acknowledging that the song is not experimental. The disagreement is not about facts but about what listeners want from a new group's first impression.
The wider context of 2026 K-pop
The Bias List argues that a vocal-focused pre-release feels surprising in 2026 K-pop, which is itself a comment on the current landscape. Without making sweeping claims about the entire industry, that observation points to a moment when many releases compete through maximalism, genre collisions or high-concept visuals. A track that relies on smooth harmonies and a bright synthline can stand out precisely because it does not try to overwhelm.
For A2O Soul, that context cuts both ways. The group benefits from novelty if listeners are craving a cleaner vocal sound, but it also faces the challenge of distinguishing itself in a crowded field. The review's comparison to RIIZE and its mention of an NCT-style universe suggest A2O is not abandoning familiar K-pop structures. Instead, it appears to be refining them. Whether that refinement feels like a fresh start or a familiar formula will depend on the listener, as the comment section already shows.
Takeaway: an introduction worth watching
The Bias List's review of 'Superstar' presents A2O Soul as a group with a clear vocal identity and a producer who knows how to frame it. The track is not positioned as a revolution, but as a confident, smooth opening statement from Lee Soo-man's new entertainment venture. Its B+ grade and the mixed reader comments reflect that it is a promising rather than flawless first step.
For anyone following the next phase of Lee Soo-man's career or the evolution of the NCT-style group model, A2O Soul is now a name to track.
The practical significance is simple: a pre-release from a new boy group under a major industry figure gives listeners an early chance to judge the sound before a full debut arrives. The Bias List has offered one detailed assessment, and the comment section has offered two very different ones. The next move from A2O Soul will show whether 'Superstar' was a one-off vocal showcase or the beginning of a sustained direction.
