WFMU has directed the creation of an incredible resource on the internet called the Free Music Archive, where the slogan is, "It's not just free music; it's good music."
Are you a podcaster looking for pod-safe audio? A radio or video producer searching for instrumental bed music that won't put your audience to sleep? A remix artist looking for pre-cleared samples? Or are you simply looking for some new sounds to add to your next playlist?
You can search by genre, or by curator, and music is available to listen to and to download. The music has been cleared for a variety of legal uses. Link to it HERE.
