Aaliyah, R. Kelly Named In Copyright Lawsuit

May 7 [10:00 EST] -- Music publisher Windswept Pacific filed a lawsuit against singer Aaliyah in U.S. District Court on Monday claiming that the singer illegally copied a 1978 song.

The dispute is over the title track to Aaliyah's 1994 debut album, "Age Ain't Nothing but a Number."

Aaliyah's album gives songwriting credit to R. Kelly for the track, but Windswept claims that the tune bears a striking (and allegedly illegal) resemblance to a 1978 top ten pop hit called "What You Won't Do For Love," [Caldwell Video, 700k QuickTime] by Bobby Caldwell. (You can listen to the songs and compare them yourself by checking out these QuickTime clips).

Aaliyah's camp has not commented yet on the suit, which was filed in Los Angeles.

The Bobby Caldwell track, by the way, recently cropped up on the soundtrack for the recent Johnny Depp/Al Pacino movie, "Donnie Brasco."
