The film's soundtrack featured 10 songs performed by the fictional band August Moon and co-written by Savan Kotecha who served as the executive music producer.

According to music producer, Savan Kotecha, the only challenge was to have "songs that felt big" making the fictional band August Moon larger-than-life.

[2] The film's music supervisors Frankie Pine and Marcus Tamkin have cited several boy bands as inspiration, notably includes One Direction, Maroon 5, NSYNC and BTS.

"[7] Kotecha wanted the original songs to "illustrate August Moon"s evolution from shiny new boy band to radio mainstays".

[17] Isabella Soares of Collider wrote "The music, written by Savan Kotecha, is boy band material, but the emphasis on only Galitzine's vocals makes the whole idea of him being part of a group, rather than a solo act, unconvincing.

"[18] Sage Dunlap of Paste wrote "The original songs are nothing more than supermarket ambience and nauseating radio replays in the world of August Moon, but for us, the boy band frenzy feels nostalgic and charming.

"[19] Rocco T. Thompson of Slant Magazine wrote "the handful of August Moon tracks aren"t trying to ape a certain boy band sound so much as serve as solid pop ditties in their own right".
