The upbeat rock song "Temporary Fix" was co-written by Horan, British songwriter Wayne Hector and two members of production team TMS. The song was born when the co-writers asked the singer what was missing from their upcoming album.

He told the guys they didn't have a "rock song" and they used Kings of Leon's hit single "Sex on Fire" as the inspiration for their "dark" song about approaching a girl at a bar. Horan adds, "It's relatable, I guess. Everyone has a grungy night out every now and then."
