I rarely listen to regular radio since I have the XM in the car. It costs about $10 or so a month - not sure of the exact amount - yearly subscription. So many channels to choose from - have 12 of them as presets but that is not enough, depending on my mood. Like John said, the sorts are better on XM, and I like it because I can listen to all the baseball games that way - they carry the entire Major League baseball schedule. And a college football schedule as well.

Also, when you subscribe to XM, you are automatically entitled to XM on yur computer.
