Dig CC Mixter is a good place to find music for use in classroom projects like videos and podcasts. The music that you will find on Dig CC Mixter is Creative Commons licensed. And, as I demonstrate in the following video, Dig CC Mixter makes it very easy to give proper attribution to the artists whose music you use.

Dig CC Mixter is one of the resources that I recommend in my on-demand webinar 5 Video Projects for Almost Every Classroom.
