Chained to the Rhythm to the high note G, while the music follows the chord progression of Am–G/A–Dm–F. In the chorus, Perry sings "Turn it up, it's your favorite song / Dance, dance, dance to the distortion / Turn it up, keep it on repeat / Stumbling around like a wasted zombie / Yeah, we think we're free / Drink, this one is on me / We're all chained to the rhythm, to the rhythm, to the rhythm." Jason Newman from "Rolling Stone" wrote, "Perry injects a subversive element underneath the ostensibly frothy song, lacing her lyrics with ideas of selfish comfortability and complacency."
