 Musically, "Trouble" is an anthemic midtempo song, that is styled in the genre of 90s influenced pop rock.The singer's voice in the song was deemed "raspier" and "more exhausted" than in the other album tracks, which are also heard during the "singalong hook".The song's instrumentation utilizes stadium drums, guitars and keyboards, while background vocals resemblant of choirs—and serve as arena rock elements—sing "whoas" repeatedly.
