Yeah, yeah, sure thing. If you would have asked me two year ago, I wouldn't have hesitated to say it's my favourite genre and that everything else is shit, but I've widened my musical span since then quite a bit... Now I just listen to anything, as long as it's good.
I'm always fond of really slow and heavy doom metal and stoner, though, and old-school thrash/death is never wrong either.
Not too keen on power metal, with the exception of Blind Guardian, who at least on their early records were really, really good, and you got more grunting that fasletto, which is a nice change from the other bands in the genre... Hehe.
I feel a bit similar towards most Black Metal bands as well - There are some exceptions, but most bands just drown in their own "über-necro-grim-kvlt-tr00"-image instead of doing good music, which is a pity...
Still, nowadays I can go from Entombed, Bloodbath and Meshuggah to Godspeed you black Emperor!, Depeche Mode, Ultravox and Bohren & Der Club of Gore(Incredible instrumental horror/doom-jazz - A must-listen, really!) in a matter of minutes, so as I said, I listen to anything that is good...
And my all-time favourite band is still Black Sabbath.
