Check out some of today's fresh offerings over at Amazon (where they're offering a free mp3 every day until Christmas in addition to the hundreds of free songs already offered on their site).
Also, you should run, not walk, to Andy Osenga's website, where you can download his newest project, Letters to the Editor, Vol. 2. The first volume yielded my favorite Osenga song of all time, "Swing Wide the Glimmering Gates," and this one is excellent as well. I love the whole collaborative concept... His web community sending in song ideas, stories and letters, even vocals and instrumental contributions on one song. Amazing.
