I dislike a huge margin of metal... Because a lot of it just seems like the most unappealing form of music imaginable... However exceptions are.

Black Sabbath
Iron Maiden
Van Halen
Metallica
Slayer
Pantera
Guns N Roses
Tool
Rage Against The Machine
Ozzy Osbourne (Blizard Of Oz at least)
Celtic Frost
Dimmu Borgir
Mastodon
Nine Inch Nails
Danzig
Mr Bungle
Opeth
Symphony X
Fates Warning
Judas Priest (Defenders Of The Faith only)
Alice In Chains
Between The Burried And Me
Kings X
Helmet
Sunn O)))
Lighting Bolt
Kyuss
Queens Of The Stone Age
Yngwie Malmsteen (Well, Rising Force)
Steve Vai (Passion And Warfare, that's all)

And if proto metal counts.

Thin Lizzy
Blue Cheer
Vanilla Fudge
Aerosmith
Captain Beyond
Rush
Alice Cooper

I have a hard time defining metal...I watched a VH1 show listing the 20 best metal bands and didn't agree that some of the 20 bands were metal. I like a lot of metal bands (Megadeth, Pantera, Testament, Slayer, etc.) and a lot of rock bands as well. I consider bands like Def Leppard, Van Halen and G N' R (old band) to be rock, not really metal. However, my favorite band is Aerosmith even though I listen to a lot of heavy stuff. I guess good music is just good music, and doesn't really need to be labeled...lol.

boo boo it's spelled Sunn O))) :p:
