i second mister's post
Some bands are better when playing live than studio record (Slipknot, Children of bodom, In Flames <--- good examples)
Or maybe your lonely, so you go into Metal looking for these friends that aren't there.
Really, It's a bunch of people screaming in your ear about how shit their life is. About how they were abused as a child and got jailed and blah blah blah.
Bunch of crap.
IMO
