I know they are not technically music but they are on my iPod so it kind of counts. My latest obsession is downloading hockey podcasts and listening to them either while I am cleaning or driving slowly in the car. It is like having Canadian sports radio. It is awesome. I bring this topic up to simply point my friends to the fact that the majority of podcasts on iTunes are free. So, for example, if you jones for soccer talk, these are a fun way to get your fix.
I currently am really into the Puck Podcast and the Face Off Hockey Radio show. They make my car time happy time.
Tussin- Richard Blade has a podcast but I haven't been able to get it to work. He has interviews with like After The Fire and ABC and ****e like that. Sounds awesome.
