Good collection, very respectable. Metal bands I see (not that you asked, and not to sound like an ass): Anthrax, Sabbath, Budgie (maybe), Diamond Head, Helloween (!), Maiden, Priest, Megadeth, Metallica, Pain of Salvation (I think), Samson (I think?), The Sword (I think?). Good stuff
Pain Of Salvation is prog metal, you'd love them.
Budgie was from the early 70's so I guess you'd call them "traditional" metal, but they seemed to be the only other band, besides Sabbath, that were embracing metal as a legitimate style.
I've repeatedly been tempted to check out Audioslave but most of what I've heard frankly strikes me as mediocre and generic no offense. There's one really good song they did though that I know, don't remember the name (Shadows of the Sun or something?).
Shadow On The Sun? I don't even care for that one.
We'll have to agree to disagree on this one. Have you heard Show Me How To Live?
The missing link in your collection: SLAYER
Oh yeah I plan on getting Seasons and South Of Heaven quite soon.
FUCK Reign In Blood.
