I love sirius for the variety of genre's that are played.
The variety on the hip hop stations... and the amount of talk... it gets very annoying sometimes. It has gotten MUCH better since they rearranged the stations, just a few months ago they would talk for literally 15 minutes, and play one song... and talk for 15 minutes, and would be talking about nonsense.
Why they feel the need to advertise what station your listening to constantly I don't get either, kinda defeats "commercial free".
Sirius, as far as I can tell, also sounds better than XM.
