I'm glad to see my suggestion of posting as many non-folk threads here was heeded! Keep them coming. Gargoyle go right ahead and start the ska thread - I'll post to that one too. Maybe another for soca would be needed.

Headbanging? First of all, it's insulting to categorize a lot of headbanging music as "stupid" as has been done above. The sub-genre is typically a simplistic form, but hardly stupid. The musicians are putting a lot of effort and energy into the music - and much of the time, they're playing some pretty good riffs too.

AC/DC
Anthrax
Beastie Boys
Circle Jerks
Clash
The Cure
Dead Kennedys
Devo
Foo Fighters

Jane's Addiction
Jimmy Eat World

Nine Inch Nails
Presidents of the U.S.A.
Rage Against the Machine
Ramones
Red Hot Chili Peppers
Sex Pistols
Skatalites
Suicidal Tendencies

To name a few.
