Americans have been indoctrinated to believe that the world revolves around us. "Welcome to America, now speak English!"
Please do not misinterpret this statement. America, that is, the United States of America, is truly a great Republic. Far from perfect, yet in its heart-of-hearts, a nation of good people who sometimes just "don't get it."
As to English music on the radio? Think about those 326 well-tested hits the next time you tune in competing Anglo-AC stations in any top 100 market in the United States.
To reiterate, there are no boogeymen lurking in the weeds. I'll stand by my original post. And why that damn KC & The Sunshine Band song ("I'm Your Boogie Man") just popped into my head is beyond me. Maybe it's those 378 spins I gave it in 1976. Gahhhh!
