Hey fellow newbie! I too use Pandora, as an app on my itouch though. They play a pretty large variety of Wilco for me(everything from AM to SBS with side projects too mixed in), which is really cool in and of itself, but it's also been great for discovering new people. Through Pandora I found Fleet Foxes and The Decemberists. I like it because even if you think you don't like a band- a song plays and you realize that you acually do!
