If you're like me, when you were a kid you encountered sundry lamentations by the adults in your life about how "kids today" don't enjoy the classics anymore. Time perception being what it is, this kind of complaint probably seems plausible to a ten-year old (however little a ten-year old will sympathize).
As you get older, though, you realize that "classics" in this context merely referred to whatever form of pop entertainment those adults enjoyed when they were kids.
