Opeth is great and all that - but, yes, we all know that No.1 is a reach for them. But fans of a certain band will put their favorites up top, we know that, as well.
Metallicarus - it's all about opinions and tastes. I have a lot of friends who are into underground 80s shit - like Watchtower, Mekong Delta, the stuff you have on your signature picture - and yet they never argue when you say that Metallica has made the best metal ever.. I mean, when I first got into them, there were no Exodus, Forbidden, Vio-lence, Testament around at the time (because it wasn't as easily accessible) - and Metallica, with its attitude AND melody really made an ideal "starting band" for a metal beginner. And now that I do have other stuff around - Testament, Pantera, Slayer, Overkill, hundreds of others - Metallica still stand above them all..
