Personally, I never liked the sound of sattellite radio when I heard it in people's cars. As a Direct TV subscriber, i used to get the XM music channels, which sounded good. But when listening through the actual XM radios in a car, it always sounds to me like an mp3 encoded at about 96 KBPS. That grainy texture in the lows, bubbly texture in the highs, type of sound. I wish they could use a bit more bandwidth or something.
