Free Tunes!
I'm not the biggest Coldplay fan in the world - I think they have some good tunes although a lot of them start to sound like the same song after a while - but they've done a very cool thing in offering a free album (presumably recorded from one or several concerts) as a thanks to their fans.
Go here to download.
Seems to be a lot of this going around: check out Jake Armerding's free release "Songs in Stained Glass" here.
And do yourself a favor and pick up his nearly co-released, secular album "Her" here.
