Metalheads: Favorite Non-Metal bands?

I'm mainly a metal head, but man do I love me some Rush. Iv'e got half their albums and my collection keeps growing! I also love more modern bands like Breaking Benjamin, and on the flip side Led Zeppelin is one of the greatest clic rock bands of all time! I would also say Black Sabbath, but I kinda consider them the fathers of metal. Still an awesome band though.
