To make up for that last post, here's a piece of delicious software that only the cool kids know about. And now, since I've told you, it's not just the cool kids anymore (ooh, snap).
Check out Songbird, the hip new open-source media player. I could fully detail its functionality, or you could just watch the little explanatory video here. Essentially, it is 75% iTunes, 20% Firefox, and 5% Winamp. Think iTunes, but without the store and with the power of music blogs. Cool.
