Pete Yorn - all I've heard is "Life on a Chain", but I have a friend who swears by him. I'll have to look into him more closely.
Paul Simon - Graceland is one of my favorite albums of all time. The rythm in it is just amazing. I guess I will try and branch out into his other albums, perhaps the one with "50 ways to leave your lover." Great song!
Jeff Buckley - I have Grace, but I can't say I listen to it much. I just get in there for the cover of Hallelujah and get right back out again. Such a heart-wrenching rendition!
Nick Cave - I have Greatest Hits, and I swear by it. My roommate is a big fan, and he says to get Murder Ballads, which I may well do. I'll definitely check out that Johnny Cash cover, as he is one of my favorites too.
Johnny Cash - Live at Folsom Prison is an amazing album, which I, regretably, have only on mp3. I've also heard San Quento (on vinyl, no less. Quite a treat).
Beck- Mutations - Another one of my favorites! And another I have only on mp3 (grrrr...)
Nick Drake- Bryter Layter - I have it but again, on mp3. That's enough to appreciate it, but not enough to really enjoy it. A good number of its songs are on Way to Blue, which I do have on CD. I would like to have the full album experience tho...
Dylan - I have Blood on the Tracks, which is fantastic, and Greatest Hits on LP, which makes me want to track down all the albums with all those songs on them (especially Mr. Tambourine Man!)
Some of my favorite music has been mentioned in this thread, which leads me to believe that the stuff I've never heard of (and there's plenty of that) will be perfect. I thank you all for your help.
