Musically the song is a 1980s-inspired pop, synth-pop, techno and disco club anthem which finds Madonna singing in her lower register. The song is set in common time with moderately fast dance groove tempo and a metronome of 126 beats per minute. It is set in the key of E major. Madonna's voice spans from D3 to A4. It follows in the chord progression of E–D–C–D in the verses, and C–D–E in the chorus, with an E synth drone playing continually.
