Your Idol

"Your Idol" is a song performed by Andrew Choi, Neckwav, Danny Chung, Kevin Woo and samUIL Lee as the fictional K-pop boy group Saja Boys in the 2025 animated musical fantasy film, KPop Demon Hunters. It was released on June 20, 2025, through Republic Records, as the seventh track from the film's soundtrack album. The song was written by Ejae, Kush, Mark Sonnenblick and Vince and produced by 24, Ido and Ian Eisendrath.

The song is used as the penultimate musical number in the film, where the Saja Boys perform it at the city stadium on the summit of Namsan to summon the main antagonist, Gwi-Ma, and feed him the souls of the magically entranced audience, before being interrupted by the arrival of the film's protagonist Rumi.

Ejae received the instrumental track of the song from The Black Label and executive music producer Ian Eisendrath with Exo references.^[1] She worked on the lyrics with The Black Label songwriters Kush and Vince. Ejae took inspiration from Christian hymns in writing the song,^[2] as well as Exo's songs "Mama" and "Obsession". The choir portion, in particular, was inspired by the choral arrangement in the former song. For the chorus intro to "Your Idol", she reversed the audio for the song "Hunter's Mantra" and harmonized it on the demo. Ejae added harmonies and sounds to evoke a cathedral and create a "creepier" atmosphere with "a kind of old Latin vibe".^[1] Ian Eisendrath brought in a Broadway vocalist to create the full choir for the track.^[1] The song's opening includes "Dies irae", a Latin sequence.^[3]

The song's use in the film marks a pivotal moment in the storyline, a "dramatic" shift to "sleek, jet-black silhouettes" as the boy band reveals their true form in full demon-like, all-black attire.^[4] "Your Idol" is a direct contrast to the Saja Boys' film introduction song "Soda Pop" which was described as a "super bubblegum-y K-pop boy band songs" similar to BTS' "Butter".^[5] The lyrics find them appealing to their fans' obsession to them, in an effort to tempt them into allowing the band to steal their souls.^[1][5][6] Debashree Dutta of Rolling Stone India highlighted "a jarring contrast" between the two Saja Boys songs, noting that "Your Idol" reveals "the Saja Boys' true nature while cleverly critiquing the darker side of fame and obsessive fan culture".^[7]

Baek Byung-yeul of The Korea Times stated the styling of the two fictional K-pop groups in the film connects to "the past and the present of Korea". In the film, the Saja Boys perform "Your Idol" in black hanbok and traditional horsehair hats, evoking "the image of the jeoseung saja, the Korean equivalent of the grim reaper".^[8] According to co-director Maggie Kang, the idea of portraying the group as "jeoseung saja" was one of the film's earliest concepts. Kang described it as "a very iconic image" that had never been explored in animation before. The scene aimed to give the film's secondary antagonist, Jinu, a "more traditional look" during the performance while drawing the audience into the dark underworld through striking color effects.^[9]

For the chart dated July 3, 2025, "Your Idol" reached number one on the US Spotify chart, marking the highest placement ever for a K-pop boy band and surpassing BTS's 2020 song "Dynamite".^[10] It became only the fourth K-pop track to top the chart, following Jung Kook's "Seven" (2023), Jimin's "Who" (2024) and Rosé's "Apt." (2024).^[11]
