I will be switching to an XM radio in a week. What are these channels like? I have some idea based on their descriptions, but I do have some questions. First, let me get this straight: KISS- like Pop 2K Nashville!- like The Highway Mix- like The Pulse/ The Blend Rock@Random- like Classic Vinyl/ Classic Rewind Now: 1) What kind of music does The Pink Channel play (it says "adult contemporary", which has always been a vague category to me) 2) How many commercials do they air in a typical hour? 3) How long are the commercial blocks? It seems as if these would be worth a listen at times. You can always switch stations during the commercials!
