"Soda Pop" was written by Vince, Kush, and Danny Chung – with production by 24, Dominsuk, and Ian Eisendrath – for the animated musical fantasy film
KPop Demon Hunters. In the film, "Soda Pop" acts as an introductory song to the Saja Boys, an antagonistic demon boy band, whose singing voices are performed by
Andrew Choi, Neckwav, Chung,
Kevin Woo, and SamUIL Lee. The song was initially recorded by Vince as a guitar demo titled "Ice Cream" roughly seven years prior to the production of
KPop Demon Hunters; this demo was later reworked into "Soda Pop" after being given by Vince to producer 24. In an interview during December 2025, Chung summarized the process of composing the song stating: Holistically, the DNA of a song like “Soda Pop” is different from THEBLACKLABEL DNA, so we had to almost think method, think outside of our own body. At first, the direction was coming back to our early demos of the song, and it was almost that it was 'too cool,' because that’s what we were used to doing—a little bit more fashion-forward music. But “Soda Pop” by design was supposed to be a little retro and ... I want to use this word carefully, but cheesy by design—an earworm and 'annoyingly addictive.' That was the direction we were given. Chung concluded that the song had a distinct 90s style boy band vibe intentionally used in the composition of the song. Chung, while discussing the song's composition, described it as a "[c]ute, bubbly, intentionally annoyingly infectious"
earworm that is "meant to lure you in". He additionally noted how the song's lyrics, though superficially sounding romantic, hold more toxic meanings to them, which serves to reflect the Saja Boys' goals in the film of deceiving and consuming the souls of their listeners. Eisendrath said that the goal of the song was to "create one of those super
bubblegum-y K-pop boy band songs in the style of a song like '
Butter by
BTS. Commenting further on the lyrics, Eisendrath explained the drinking in every drop of the 'you're my
soda pop' metaphor, saying that "[the Saja Boys] feed on souls. So it was like, 'How do we say that in a way that appears [like an] innocent, fun, K-pop bop, but actually it's expressing who these people really are and what they're really after? == Critical reception ==
