"I'm going to teach you how to scream"

Why do emo kids try to teach the world how to do death metal vocals? I always assumed they were just good at crying, not death metal. This worries me, probably not long before we have a emo-death metal band. Anyways, our friends over at Spine Language compiled a bunch of tutorials that you can watch and cringe to below. I can't wait for the day when someone as big as Corpsegrinder states he learned to scream from a youtube video.
