What about if you don't even have an iPod? I'm glad I don't. Takes time away from TT... :)

I check out the NPR podcasts. Free your mind, listen to NPR.

You don't need to use iTunes... XD

Here's some good audio podcasts I've found
Informer and Snitch (IAS)
Informer's Entertainment Buzz (IAS)
Fat Cracker Report (By Hardly Worthit)
Nightly Nirvana
Let The Zep Out Week In Review

First two are verryyyyy explicity, the third one is quite liberal (being a political podcast), and the last two are some podcasts that are almost like listening to a good radio station, along with some weekly news mixed in regularly.

(Ohh yeah, the main reason I like Fat Cracker Report is because he plays Big Money at the beginning and end, and you know Geddy can't resist Geddy.)

If you like some jammin music Umphrey Mcgee has a few different streamming & downloadable podcasts..but only if you like jammin tunes :P

I occasionally listen to the behind the scenes of Disney Podcasts
