I am amazed

It staggers my mind how ignorant people can be about metal. Fuuuuck.
First, it is "Megadeth" not "Megadeath".
Secondly, Underoath, My Chemical Romance, and the Red Jumpsuit Apparatus are not metal.
Thirdly, metal is far from dead, you just don't hear shitty radio-rock/metal that much anymore because it has been replaced by emo/screamo rock.
