This music is found in genres such as Glam Rock (Bon Jovi), Glam Metal (KISS, Twisted Sister), Nu metal (Slipknot, Korn), Deathcore (Bring Me The Horizon, As Blood Runs Black), some Metalcore (Attack Attack!, Iwrestledabearonce), Alternative metal (System of a Down, Papa Roach), some Hard Rock (people call AC/DC and Led Zeppelin metal).
Most mainstream metal sucks because of its very watered-down MTV style, which most metalheads dislike strongly.
Idiots, who have no clue what they're saying, call Led Zeppelin or AC/DC metal. This is not true at all. They both have told their fans that they play hard rock, not metal.
Bon Jovi is not metal and never will be. Their style is too love song oriented and they have appeared on shows like American Idol, which totally throws away metal completely no matter who is on that show.
Korn and Slipknot are not even heavy enough to be metal. Their lyrics, image, and singing is too mainstream to be metal. People call Slipknot death metal? Haha! This is a disgrace to true death metal, which was created by amazingly talented bands. That is just pure blasphemy.
Deathcore ruins death metal by invading it with talentless hardcore punk. Don't get any metalhead started on that...
Real metalhead: Go listen to real metal such as Death, Carcass or Nile.
Fake metalhead: All that stuff is way too amazingly talented for me. I think I'm gonna go listen to Slipknot now.
