hahaha. Hmm, trying to think of bands is hard. Okay, deathstars, bullet for my valentine, killswitch, in flames, arch enemy, cradle of filth, dimmu borgir, atreyu, still remains, bleeding through, dissection, protest the hero, maroon, final breath, kreator, nile, lamb of god, emperor, foul body autopsy, the black dahlia murder, anthelion, black sabbath, judas priest, axe wound, wintersun, stabwound, machinehead, mastodon, crytopsy, gorguts, ...
I hope that's enough, it could go on for days. I like a mix of all the different types.
