Well, now that everyone is putting down so many bands, I quess I'm putting every band here then (not in any particular order):
Tool
Korn
Lordi
Poets of the Fall
Megadeth
Nightwish
Sodom
Kreator
Metallica
Black Sabbath
Ozzy Osbourne
Iron Maiden
DIO
Dope
Rammstein
Serj Tankian
A Perfect Circle (not so much, but they were quite good)
Disturbed
Motörhead
Mokoma
That's what I can remember right now for metal and rock. I also listen to alot of soundtracks, here are some of my favourites (not in particular order):
Shadow of the Colossus (epicness...)
Left 4 Dead 2 (not really a soundtrack I think, but the songs in that game are awesome, and I have them on my phone)
King Kong (Peter Jackson's)
Hulk (the 2003 one. That movie has an awesome soundtrack, altho the movie itself was a flop)
Carrie (It's good. Couple of songs I really love, but the others are not so great, altho they are good... anyway)
Lord of the Rings: Fellowship of the Ring (goddamn, it's epic)
Godzilla theme... just... what more can I say?
Oh and
this.
That's all... and I also like Dead or Alive too. They are good.
