“Into the Groove,” Desperately Seeking Susan
Considered by many to be Madonna‘s first breakout single, “Groove” appeared in Susan Seidelman’s 1985 film but not its official soundtrack. (Madge originally penned another song, “Desperately Seeking Susan,” but it was scrapped in favor of “Groove.”)
This wouldn’t be the last time a Madonna song that helped launch a movie was omitted from the soundtrack. Girl can’t catch a break!
