Hmm.. Not sure I'd classify Avenged Sevenfold as "heavy metal" or even just plain "rock". More of a alternative rock or pop-rock. I know a lot of fans of theirs will defense them..but, listen to one of Avenged Sevenfold's songs then Black Sabbath.. I don't think there's any doubt as to what genre Avenged Sevenfold is.
If I were to vote (like the user before me, it seems a little superficial..), it wouldn't be for Brian Haner Jr. or M. Shadows.. Call me crazy, but I don't find them attractive at all.
V There's a poll somewhere in the Internet (I think of the magazine Revolver,not sure) about the hottest rock star. *rollseyes* I find it quite superficial.
