Love my XM. Deep Tracks, Bluesville, Outlaw Country and the Broadway Channel are my top presets. Lately I've been listening to the 70s on 7, reliving my childhood (well, adolescence anyway...)
Oh, and MLB. That's the reason I first got it. I also used to like XMPR when they had Bob Edwards. Then they fired him and dropped the channel. MLB is the only non-music channel I bookmark now.
Only local radio I listen to is NPR and sports talk. And not really a lot of sports talk...it's kinda painful most of the time.
