Forums: Help needed for this movie title!

This futuristic animated movie I believe was released in the early 80's, around the time of Heavy Metal I think. The movie has the evil character searching for a certain tone or pitch from a voice that he discovers in a club. The womans voice however is the girlfriend of one of the singers and guitar player in the clubs other bands. Actually, they may be auditioning. Anyway, the girls is kidnapped and the boyfriend pursues. The evil guy is somehow defeated by her voice somehow. The characters may have the slightest doglike features. Been looking for a long time, but can't find any help. Please reply if you think you might know. Thanks.
