I like some of his songs, but I am not a big fan. I am always surprised how many people get mad at me or look at me like I am crazy when I tell them that. I like some of his stuff, but it is just not my favorite style I guess. I think I was tainted by the copycats who weren't as good. I'll probably pick up his best-of album and see where it goes from there. I certainly do have some worse music on my iPod.
To be honest, he was popular when I was in school and getting into Led Zeppelin, Rush, Yes, and other bands. It just wasn't on my radar at the time.
