I'll admit it too, I just don't get XM (more accurately, I won't get XM)--you mean pay-radio for the car?!? Puh-leaze.

I really have no value in trying to capture unlabled music for future playback, but I have great value in being able to capture talk shows and news broadcasts to enable timeshifting them for, say, during a commute (would that I had one right now... ).
