It isn't "country". Of course when I was listening to the am transistor radio on the beach, the radio station I listen to played top 40. There was the standard crap, but there was rolling stones, beatles, "love is blue", classical gas, boy named sue, okie from muskogee, frank sinatra, loving spoonful, hendrix, ... and so on and so forth.
Those pesky kids of today are missing out on the variety us old fogies grew up on. Maybe -- perhaps their listening is as varied as ours was, but they are not getting it from radio.
