I've had an XM subscription for years and I cannot go back to normal radio. The selection of stations is unreal. Our receiver has been alternating between XMU to Flight 29 for some time now. If you get a minute you should log on and check out Flight 26 or check out Channel 43 XMU which is Indie/College/unsigned bands. You can view their line up by clicking on the following link:
