On August 25 1987, Causing a Commotion was released as the second single from the soundtrack album Who’s That Girl, by Sire Records. Causing a Commotion was 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.
Today In Madonna History 
That honor belongs to Madonna because she has caused a commotion for nearly 40 years in care of her brilliant music and her wonderful art!
I was really hoping this would have been a much bigger hit. It is just such a Madonna song. Would like to have seen it on the compilations.
