Yeah, I see where you're coming from.Maybe it is because everyone thinks they should be a fan. With a name like 'slayer' it should be a heavy metal staple, you dig?
I wouldn't have expected them to be complex enough for you anyway.Slayer has five special songs (Seasons in the Abyss, Angel of Death, Raining Blood, South of Heaven, Black Magic) and the rest all sound the same. I don't like them.
