Thanks everyone for the suggestions.
I listen to a lot of podcasts:
Dreamstation.cc (I actually burn this one to a CD and listen to it on the way to school (I put it in the stereo and my dad and I enjoy it)
Gamertag Radio (Although I dislike the ghetto/rap aspect, they're usually informative and interesting)
Gaming Steve (No equal)
Geek Speak Radio
GeeksOn
PCGamer Podcast (if only PC Powerplay did a podcast, as an aussie, they're the ones I read...)
TWiT (Dvorak is a legend)
Xbox Live's Major Nelson (last week he interviewed the guy who coined the name "GamerTag"
I also highly recommend the Ricky Gervais podcast, which are all absolutely hilarious (I've seen Ricky in things like Extras and The Office, so I knew it would be).
