theres a lot of good "metal" bands but way too much crap.
bands worth listening to (not limiting it to just METAL, but influences)
cryptopsy, suffocation, dying fetus, skinless, YOB, necrophagist, napalm death, morbid angel, noothgrush, man is the bastard, brainoil, cruevo, sleep, monarch!, grief, moss, asunder, dystopia, loaded for bear, hombrinus dudes, endless blockade, wake up on fire, gorguts, eyehategod, etc blah blah blah
bands not worth listening to because they suck:
manowar, rhapsody, dragon force, any other epic metal band....lame
