Actually the bit rate on newer XMradio sets and satellite channels is much higher, but that's not really the benefit of the higher quality of sound found from satellite radio like XM.
FM is a modulated radio signal and when the signal encounters frequency noise it adds that noise to the signal\station sound. Satellite radio is able to filter out noise by using rate sampling and noise elimination algorithms when uncompressing, thus a clearer sound. FM and AM technology is rather "dumb" technology it only knows to repeat what it receives including static.
As for hearing new great talent, there is FAR more offered on XM radio than local FM. I guess if you want to limit yourself to only hearing talent in the DC area, then local DC radio stations would do that. Personally I can't find any talent on any DC radio or playlists I like, except maybe Elliot, but he is broadcast nationally.
I'm not knocking local radio, but nothing compared to XMradio. I sometimes listen online to local radio stations at beaches or places I like. The ads are half the fun, nothing like hearing waves 2 feet, lifeguards are asking to be becareful today and there will be a crabfest at the fire dept tonight. Or, small town bum-f radio that really cracks me up; "Mrs. Johnson cow got loose."
