Key facts about ‘Soda Pop’ and the Saja Boys are summarized below.

Who sings the Soda Pop in KPop Demon Hunters?

Who are the credited vocalists on the track?

• The singing voice of Mystery Saja is provided by KEVIN WOO, a former member of U-KISS (The Independent).
• Additional vocalists on “Soda Pop” include Andrew Choi, Neckwav, Danny Chung, and samUIL Lee.

What is Kevin Woo’s role in the Saja Boys?

Woo, who rose to fame as a member of the K-pop group U-KISS, is credited as the singing voice of Mystery Saja — one of the seven fictional members. He shared a cover of “Soda Pop” on his YouTube channel, confirming his role (KEVIN WOO’s YouTube channel). The Saja Boys as a whole are voiced by the five named artists, with each contributing to different vocal parts across the film’s soundtrack.

The implication: “Soda Pop” is a production of multiple songwriters and session vocalists, not a single idol’s showcase — which is exactly how many real K-pop group tracks are built.

Is Soda Pop from KPop Demon Hunters a real song?

Is the song available on streaming platforms?

• Yes, “Soda Pop” is a real song released as part of the KPop Demon Hunters soundtrack. It is available on Spotify, YouTube (via official lyric video), and Netflix (within the film and as a standalone music video).
• It has a Wikipedia entry cataloging the soundtrack details (Wikipedia).

Does the song exist outside the movie?

Yes — “Soda Pop” was released as a single from the soundtrack on the same day as the film’s premiere, June 20, 2025. It functions as a standalone K-pop track, complete with a lyric video on Netflix’s official YouTube channel.

The pattern: Netflix treated the song as a real music release, not just background scoring — signaling the studio’s ambition to compete in the K-pop streaming space.

Who sang as the Saja Boys?

Who provided the voices for the fictional Saja Boys members?

• The Saja Boys’ singing voices were provided by KEVIN WOO, Andrew Choi, Neckwav, Danny Chung, and samUIL Lee.
• KEVIN WOO is a former member of U-KISS and is explicitly credited as the “Singing voice of Mystery Saja” (KEVIN WOO’s YouTube channel).

Are any of the voice actors real K-pop singers?

Yes: KEVIN WOO is an established K-pop idol with a decade-plus career. Andrew Choi has worked as a songwriter and vocal director for several K-pop acts. The other three — Neckwav, Danny Chung, and samUIL Lee — are primarily producers and session vocalists, though some have solo work.

The trade-off: listeners get a polished studio track with experienced K-pop talent, but there is no group to follow, tour, or stan — the Saja Boys only exist on screen and on streaming platforms.

Does BTS sing Soda Pop in KPop Demon Hunters?

Is BTS involved in the soundtrack?

• BTS does not sing “Soda Pop”. The song is performed entirely by the fictional Saja Boys (voiced by the five artists listed above). Multiple media outlets have confirmed BTS has no involvement.
• The Saja Boys are inspired by the concept of a K-pop boy band but are not directly based on BTS.

How do the Saja Boys compare to BTS?

Some fans speculated a connection because both groups have seven members and perform similar pop-dance genres. However, the film’s director, Maggie Kang, described the fan comparisons as “a little surreal” and stated they did not intend to copy any real group.

Six points, one pattern: the comparison is almost entirely fan-driven. No official documentation from Netflix or the film’s production team links the Saja Boys to BTS beyond the generic “K-pop boy band” archetype.

Are Saja Boys based on BTS?

What did the director say about the inspiration?

• The director of KPop Demon Hunters said the Saja Boys are not directly based on BTS, though they were influenced by the global K-pop phenomenon.
• The Saja Boys have seven members, which is a common K-pop group size, but no specific member parallels exist.

What are the similarities and differences between Saja Boys and BTS?

The comparison is largely fan-driven, not official. Both groups operate in the K-pop space and have seven members, but the Saja Boys are fictional characters within a supernatural action-comedy, while BTS is a real-world group with a decade of music, touring, and cultural impact.

The pattern: by denying a direct BTS connection while still building a seven-member group, Netflix gets viral conversation without legal or reputational risk.
