I am in the process of reading this legal guide for podcasters. Yes, a real legal guide. It even has stuff in there like:
220.127.116.11 Licenses You Will Need.
(a) Licenses For Reproduction And Distribution Of Musical Works.
Yeah. Quite boring reading. But, good stuff none the less. I recommend any podcaster get their hands on it. It might just save you some headaches down the road. What may be seemingly innocent now could be a lawsuit when your podcast has a following of a few thousand people.

There is a PDF version available which I have printed to read and to store for future reference.
