We listen to 33 (First Wave), 35 (Siris XMU), and 28 (can't remember the name!) a lot!

Our subscription is a gift from family. It is up for renewal right now. We don't have cable, but I think I'd pay for XM. I really love their NPR talk stations, and I feel like I have more exposure to new music through them. We don't get anything other than top 40 or country in our area!
