Who Sings ‘Soda Pop’ in KPop Demon Hunters? The Saja Boys

A fictional demon-boy band called the Saja Boys became a real chart sensation with the song “Soda Pop” from the Netflix film KPop Demon Hunters. Behind the animated characters are real session singers, and the story of how a fictional K-pop group became a real-world phenomenon is stranger — and more intentional — than most people realize.

Who sings the Soda Pop in KPop Demon Hunters?

Kevin Woo as Mystery Saja

The lead vocal on “Soda Pop” belongs to Kevin Woo, a former member of the K-pop group U-KISS. He provides the singing voice for Mystery Saja, the masked leader of the Saja Boys. The official lyric video posted by Netflix Family on YouTube credits him explicitly, and Apple Music’s track listing confirms him as the featured artist on the song. For fans trying to pin down who sings the Soda Pop in KPop Demon Hunters, Woo is the clearest answer available.

The official lyric video evidence

Netflix’s YouTube channel released a lyric video for “Soda Pop” that lists Kevin Woo in the description alongside the track’s producers. The video has accumulated millions of views, and comment threads show that many viewers initially assumed the song was performed by a real K-pop group. This confusion — and the film’s deliberate blurring of fiction and reality — is central to why the Saja Boys singers have become a topic of intense curiosity.

List of Saja Boys singers

The Saja Boys’ singing voices come from three real-world vocalists: Andrew Choi, Neckwav, and Danny Phantom. Each has a background in K-pop songwriting and production. Andrew Choi has written hits for groups like EXO and NCT; Neckwav is a producer and vocal director; Danny Phantom is a songwriter and performer active in the K-pop scene. According to Wikipedia, these three performers provide all the vocal tracks attributed to the Saja Boys in the film.

Roles in the soundtrack

The soundtrack credits several performing entities: KPop Demon Hunters Cast, HUNTR/X, and Saja Boys. The Saja Boys appear on two tracks: “Soda Pop” and “Your Idol.” Apple Music notes that the Saja Boys’ villain track “Your Idol” involved Black Label producer Ido, Theater Camp songwriter Mark Sonnenblick, and EJAE. This production team gave the songs a polished, industry-grade sound that helped the soundtrack reach No. 8 on the Billboard 200, as Music Business Worldwide reported in July 2025.

The implication: these are not amateur voice actors but seasoned K-pop creators who shaped the sound of real bands.

While the Saja Boys share BTS’s polished performance aesthetic, they differ in narrative role. In the film, the Saja Boys are antagonists — a demon boy band that the heroines must defeat. This inversion turns the typical K-pop fan fantasy into a conflict. The group’s songs, especially “Your Idol,” lean into dark, theatrical production that distinguishes them from BTS’s broader catalog. The comparison exists, but the Saja Boys are a fictional take on the concept, not a direct replica.

The group’s lineup, music direction, and debut timeline have not been officially confirmed.

Announcements and plans

News outlets have reported that the Saja Boys will perform as a real group, with potential tours and original music beyond the film’s soundtrack. The decision reflects a broader industry trend of fictional K-pop groups crossing into real performance, as seen with other media franchises. For fans searching are the saja boys singers a real band, the answer is emerging: not yet, but the machinery is in motion.
