The other WDW based podcast that I listen to is Inside The Magic. Ricky Brigante presents a good padcast as well, although I still prefer WDWRadio. Whereas Lou takes a fairly positive approach to all things Disney, Ricky will occasionally lean the other direction on certain points/issues. It's by no means a negative podacst, but it does differ from WDWRadio.
The other podacst I listen to is the Disneyland based Paul Barrie's A Window to the Magic podcast. This podcast most often features recorded audio from the parks, both past and present. An occasional interview or retrospective is inserted, however most of the shows are meant to be as if you're actually walking around with Paul or a guest host.
There are many others out there as you know, however those are the three that I listen to.
