The Spoken Alexandria Project is a library of free, Creative Commons tagged, audio stories for your enjoyment. They come in a variety of flavors, including podcasts. The first story listed is an SF short story by Kelly Link called Most of My Friends Are Two-Thirds Water. I need some of those, most of my friends are two thirds rocks. At least in the cranial area.
