Gangsta

This is killing me, but I can't figure out/find what song was playing when Marcia was performing in the dance competition at the end of the movie. It started out with "Gangsta" ... and I believe one of the lines was "they say you wanted for shooting me." It was playing as Larry and Priest were going at it. Its not on the official soundtrack and it doesn't seem to be listed in the credits of the movie. Help please!
