for the last soundgarden list. you forgot 'fresh deadly roses' 'karaoke' and 'fluttergirl (demo)' all of which i'd choose over most of those b-sides. hehehehe

a two disc best of and they have only two full cd's out yet? isn't that a bit strange?

I just picked them because I know thier songs better than any other artist (excluding Björk but you can't make me choose those). They have a lot of good b-sides and unreleased tracks. To my knowledge they still haven't officially released "Idiot". Still, I had enough songs to make two discs. I even forgot to include "Sparks".

Here are my actual mix CDs of Metallica:

CD1:
01 - Battery
02 - Fuel
03 - Enter Sandman
04 - The Thing That Should Not Be
05 - Unforgiven
06 - Hero Of The Day
07 - Wherever I May Roam
08 - Sad But True
09 - Master Of Puppets
10 - It Ain't My Bitch
11 - Leper Messiah
12 - One

CD2:
01 - For Whom The Bell Tolls
02 - Holier Than Thou
03 - Hit The Lights
04 - Fight Fire With Fire
05 - Through The Never
06 - Disposable Heroes
07 - Fade To Black
08 - Jump In The Fire
09 - Die Die My Darling
10 - Trapped Under Ice
11 - Welcome Home (Sanitarium)
12 - No Leaf Clover
13 - Call Of Cthulu

I could be a little off on the actual song titles since I was trying to name them as I was listening to the CDs.

Dare I touch the untouchable?
