The fact that Madonna would give the song such an unconventional debut shows how strong her popularity was at the time and how big of a hit the song really is. With filming finishing right before Like a Virgin was out, Desperately Seeking Susan swiftly became a Madonna vehicle before its release. Ratings were lowered specifically to accommodate the star’s teen fanbase and lead Rosanna Arquette was seen as a supporting actress in Madge’s shadow. The unpolished demo didn’t even land on the film’s soundtrack and was only available as the B-side to "Angel" in the U.S., but it’s still regarded as one of Madonna’s best dance tracks. —Hazel Cills
