Mercedes Benz Podcast. No, it isnt about cars Its about upcoming international artists in R&B, Jazz, and such.
Its basically a radio-like audio thing on iTunes. You subscribe to a podcast and your iTunes will auto-update (usually) you with new episodes for free. It can range from music (I listen to a lot of trance and jazz) and politics (they have news ones with CNN and stuff) into languages (lessons in Spanish and Italian and so on) and hobbies (A lot of GR ppl like PC Gamers and I sometimes listen to the WoW podcast) http://www.apple.com/itunes/podcasts/ <-- This will help ya
Since i am a bit of a Wheel of Time freak, the dragonmount.com podcast is good. It basically goes over characters etc, to build a greater undersatnding, and it helps me remember stuff from earlier in the series.
