If we're going to get into older music, I have to mention the stuff I grew up listening too.  I wasn't alive when it came out.  But when I was younger, my dad got me into it.  I'd have to say....
Frampton
Boston
Supertramp  were the big ones.
Also, with my buddies, I got into Zepplin,  Van Halen, and Sabbath.  And yes Theridos, While Ozzy was in the band. soooo good in those days.
