Bruce would have to be at the top of my list.

Out of most of today's "Rock" bands, I think the guy from Creed actually sings nice on a lot of songs compared to most other groups.

Can't stand the whacko from Chilli Peppers. Can't figure out why everyone likes them so much. 8 out of every 10 of their songs sounds just like the last one. Same stop start tempo, same bridge, same boring content.

Plenty others to challenge the "Official" list.
