Why don't outstanding musicians and vocalist's get national or worldwide attention?

Does John Q. Public even have the capacity to understand when they're hearing something exceptional? Or do they just respond to a drum machine and a synthesized handful of notes accompanied by a pitch corrected voice "singing" repetitive lyrics?

Does it take a hot female singer in a skimpy outfit "twerking" or a handsome square jawed dude in a cowboy hat?

Would the American public recognize talent if it bit them on the a*s?

These are just questions. Your thoughts please.
