"Causing a Commotion" is a song by American singer Madonna from the soundtrack to the 1987 film "Who's That Girl". It was released as the album's second single on August 25, 1987 by Sire Records. Its Silver Screen Single Mix later appeared on the 1991 UK compilation EP "The Holiday Collection". Written and produced by Madonna and Stephen Bray, the song was inspired by Madonna's relationship with then husband Sean Penn, and his abusive and violent nature. Containing a dance-oriented, up-tempo groove, the song begins with the chorus and is accompanied by a four-note descending bassline and staccato chords in the verse.
