Who Are the Singing Voices?

While the main actors provide the speaking voices, many songs feature dedicated singing voices from real-life musicians to capture authentic K-pop energy. This separation allows for high-energy performances, as seen in the soundtrack's success, which topped charts and became the first film soundtrack with four top-10 Billboard Hot 100 hits. Tracks like "Golden" and "Soda Pop" highlight this, with contributions from artists inspired by groups like TWICE and BTS.

This dual approach—actors for dialogue and musicians for songs—enhances the film's cultural authenticity, drawing from Korean mythology and modern K-pop. Forums like Reddit note fan discussions on how these voices elevate the soundtrack, making it a "cultural phenomenon."
