isnt it more an argument of why you listen to music, how you listen to music, and if your not a "music only guy", your a radio guy, meaning you like music, talk, comedy, and live sports, CNN channel, etc...
These are not necessarily the same markets.
Like buying a Lexus, vs. buying a Camary. Sure, its the "car market", but really not the same market one bit. Different income levels, different needs, etc...
