What a twat the author of that article is. What is this, 1965? "12 yr olds have nothing better to listen to than the Beatles?" Well, on that he's right, most modern music is total shit! 
But who can argue with this turd of wisdom in the article?:
"When headshots of John, Paul, George and Ringo — two deceased, two septuagenarians — adorn adolescents’ walls from 1963 to 2013, something is either wrong with pop culture or wrong with teenagers"
That's more an indictment on the absolute shit that is being produced today than anything against the Beatles. ...
