Bought on a whim, but it really opened my eyes to some bands I had never heard before like the Shins, Zero 7, Colin Hay, Iron and Wine and Thievery Corporation. Even has a cool song by Simon and Garfunkel that I had never heard called "The only living boy in New York" and a great song by Coldplay.
It's not as good as Wilco (a great choice) but, for me, it was really cool hearing all these new and very talented bands. Take a listen on Amazon to see if it's your cup of tea. Warning: some of the songs on Garden State take a while to "warm up" to but if you give them a chance, you may find something new. Cool stuff!

PS- Really check out The Shins and Zero 7. Strange names but really cool music. Also, Frau Frau (think that's the name). I love this compilation and will most likely pick up some of the other recordings from these bands.
