Seeqpod today offers up a huge list of tasty nuggets from Sufjan Stevens. The songs range from long-titled instrumentals through interesting takes on Christmas tunes, litrugical ballads and drastically different covers, songs about states and lots of works with esoteric references.
I've put the songs in alphabetical order because his work has been so vastly different song by song, album by album. Put this one on random and let it blast.
