Don't have direct experience with it but our head Crestron tech provided us with login to show our clients the available stations.

I just looked and there are 19676 Radio stations and just under 11000 Podcasts.

The cool thing about the Crestron Audionet card is that if there is a local station that you want to listen to you can add it to the list (providing they stream on the net).

I am not too sure about Pandora as we are in Canada and don't have access to it.
