Here is what I can recall I used to use to tune when I was big into audio don't laugh

Top Gun Soundtrack
The Crow Soundtrack
Lost Highway Soundtrack (emphasis on tracks 6 and 13)
Radiohead: OK Computer
ZZ Top: Eliminator
Stevie Ray Vaughan and Double Trouble: In Step- Riviera Paradise and Crossfire
And for low end muddyness and low freq. extension: Silicon, The Bass Experience

I think the self titled Audioslave CD sounds great too, just begs to be cranked up, NIN Pretty Hate Machine, and again, don't laugh, but Tears for Fears the Millenium Collection Disc is good- somewhat dynamic
I agree with you on the Nirvana Unplugged, and Buzzard-the entire Sin single with Get down make love rocks!

 

What problem was that? I really enjoy the redemption/story songs they sing about.

 

that while the music is ok, the recording quality stinks

 

^^
Yeah that's true for some of the songs.

 

Depends on the mood more than anything but all the songs hit in a different way and really show the range of the system. I was surprised how awesome Killing in the Name sounds. It's by far the best on this list with Night Train right on it's heels.

Here are some that really make me appreciate having a decent sound sytem in the Z:

Radiohead - OK Computer (Track 5 "Let Down" makes my stomach melt about 70% into the song, if you listen to it you'll know)

Duncan Sheik - All of his CD's sound great

Ben Folds - Rockin the Suburbs (Track 6 "The Ascent of Stan)- Very overproduced, very good quality

Guster - Lost and Gone Forever CD (someone already mentioned this)

Jamiroquai - Synkronized or Dynamite sound awesome (I would say the sound is "juicy", I can't think of a better word)

 

Good call, I forgot that song existed.

 

Sublime Sublime
