The album is a departure from the band's earlier material, retaining a pop punk style but adding regular unusual arrangements and instruments in many songs, with varying songs including a Hammond organ, quirky rhythms, strings and synths. Changes are especially evident in the album's three songs written by Diggle, who had written and recorded three further songs with the band for the album but which were accidentally left off the album when it was handed for publishing, although the unreleased songs were released as bonus tracks in the Japanese release. As such, "All Set" leans heavily onto Shelley's material. Barker's drumming style was said to show more flair, whilst the record is said to "reflect their maturity and approach to relationships that the early singles just couldn't."
