The film featured three original songs written by Billie Eilish and Finneas O'Connell, the latter appeared as the member of the fictional boy band 4*Town.

Tom MacDougall, executive producer of Disney Music Group, had been a fan of Ellish's work since "Ocean Eyes" and claimed that he was impressed "by the breadth of the territory that their songwriting and performing covered".

"I wanted to score to represent those uncomfortable and confusing feelings that we all encounter in our journey to adulthood [...] It's a crazy mix of musical genres, from New Jack Swing to '90s boy-band, traditional Chinese sounds and Western orchestra.

The result is wild, raucous fun, with traditional Chinese instruments flavoring an often fast-moving, big-beat orchestral groove that propels Turning Red to its satisfying conclusion."

The resulting score comprises a whole slew of genres ranging from boy band beats, traditional Chinese music and more Western hip-hop, along with orchestral sounds.

Music also became a major plot driver of the movie, with a fictional boy band becoming the forces that unite Mei and her friends at the same time as creating conflict between the mother and daughter duo.
