Metalhead right here, although I generally stick to the more brutal side of things. A list of my favourite bands, some brutal, some not so:

Dying Fetus
Pre-1995 Cannibal Corpse
Morbid Angel
Six Feet Under
Kataklysm
Opeth
Iron Maiden
Disgorge
Mortician
Mudvayne
Korn
Hate Eternal
Bloodbath
Meat Wallet (a local band)
Elvenking
DragonForce
Psycroptic
Cryptopsy
Nile
Murderdolls
Zyklon

There's prolly more but I can't be fucked thinkin' of 'em. On top of all that i listen to some dance music, Cypress Hill, Benny Goodman, classical and all forms of jazz. I feel no shame, nor do I feel dirty in any way. Music is music. If you enjoy it, you enjoy it and a stereotype should hardly make you feel any worse about it.

Peace
