Check out some cool sites:
NoiseTrade - Basically you can either pay what you want ($1-25) OR give the email addresses of 3 friends you want to share the music with. They have some great stuff! Sandra McCracken's Gravity | Love, Derek Webb's The Ringing Bell, Waterdeep's Heart Attack Time Machine and many others from the likes of Matthew Perryman Jones, Alli Rogers and Katie Herzig. Derek Webb started this site with some business partners. You can read about it all on the site. I think it's a cool thing... the wave of the future!
::UPDATE:: Sixpence None the Richer's new EP, My Dear Machine, is up here. Get it while it's hot!
Daytrotter - This site is pretty self-explanatory. Nearly every day, there's a new article/interview with some cool indie band and 3-5 downloadable live tracks. Gotta love it. I've found great stuff from Dave Bazan, Death Cab for Cutie, Erin McKeown, Jessie Baylin, Andrew Bird, John Vanderslice, The National, Of Montreal, Spoon, Rogue Wave... You get the picture.
