From what I've had the misfortune of hearing/seeing lately, metal is getting fused with trance/house/techno and subgenres of it are lending a hand to create abominations such as Brokencyde.
For fuck's sake lets hope that doesn't get out of hand.
My step brother does not listen to music. He does not own a single album. It frightens me.
Fuck off
My personal "next big thing in metal" has been to listen to other music.
Highly recommended.
