Considering Bowie's love of Daniel Johnston and the roll call of impressive artists involved in the project, it's a wonder why he never contributed to this album:
Disc: 1 1. My Life Is Starting Over Again / Teenage Fanclub with Jad Fair 2. Don't Let The Sun Go Down On Your Grievience / Clem Snide 3. Impossible Love / Gordon Gano 4. Living Life / Eels 5. Walking The Cow / T.V. On The Radio 6. Good Morning You / The Rabbit 7. Sorry Entertainer / Calvin Johnson 8. Devil Town / Bright Eyes 9. Dream Scream / Death Cab For Cutie 10. True Love Will Find You In The End / Beck 11. Go / Sparklehorse w/ Flaming Lips 12. Blue Clouds / Mercury Rev 13. Love Not Dead / Thistle 14. Like A Monkey In The Zoo / Vic Chesnutt 15. Dead Lovers Twisted Heart / Starlight Mints 16. Story Of An Artist / M. Ward 17. The Sun Shines Down On Me / Guster 18. King Kong / Tom Waits
Oh, I forgot to mention, Johnston has already covered Bowie (albeit with different lyrics). You can listen to it here (scroll down to play track 8 titled 'Monsters').
