I'm thinking about adding satellite radio to my car. I spend a lot of time driving and there is nothing at all going on in radio today. In Boston every rock radio station plays almost the same playlists , even the clasic & oldie station play the same 50 songs over & over. I'm not happy about paying for radio content but for less than a CD a month I can get a big variety of musical choices(I think).Seems like I'm always listening to either talk radio or a CD in the car .Well has anyone jumped onboard XM yet? Are you happy with the sound quality and musical programming?
