I've never been a true metalhead, but I have enjoyed my fair share of it. (In fact, 12 years ago I was at a metal show in Ft. Worth, TX where a piece of actual metal flew off the stage and bounced off my head. It was awesomely ironic.)
UPDATE: I've never been a huge fan of "screamo" -- which is what this is called, for the older generation (ie. Dad) -- because you can't understand ANYTHING. However, I do think I picked up a "1 IN 5 HAUNTED!!!!!!!!!!!!" in there.
