I'm a subscriber to last.fm and find its "radio" feature interesting. Based on selecting an artist that you like, it will play songs from similar artists. I have discovered a few new artists -- some popular, others less well-known. Starting with The National and Johnny Flynn, I have found Mumford & Sons, Noah and the Whale, etc. And Angus and Julia Stone! I did not realize that they are so well-known in Australia but apparently not known here in North America. yet?! This is an absolutely stunning set of songs... simple melodies, haunting vocals. A gem!
