In no particular order besides Opeth; formatted as "Group (Genre)":
Opeth (Progressive Death Metal)-I really love them, saw them live
In Flames (Melodic Death Metal)-not bad but turned off slightly because a friend i dispise listens to them all the time
Soilwork (Melodic Death Metal)
Children of Bodom (Melodic Death Metal)
Dark Tranquillity (Melodic Death Metal)-Saw them live with opeth for the first time, didnt really like them but their recorded music might be better
Lamb of God (Death Metal)-Cant get enough of them
Rush (Progressive Rock)
Dream Theater (Progressive Metal)-Been really getting into them, not bad at all
I have a demo of Headstrong from Trapt before they got big. Its really different and good and now that ive heard the demo i think the real one sucks. They changed some of the better stuff they had.
My music tastes have changed some (I posted last year in this thread)...
I don't really like Metallica anymore, I got tired of them. My favorite has to be System of a Down, just not their new album.
I like foreign metal, mostly German such as In Extremo and Megaherz.. I don't understand it but it is pretty good music.
System of a Down used to be good pre Ozzfest99. Back then they where freakin awesome as ****. Now its meh. I am liking Coheed and Cambria now and Taking back Sunday.
