There are some that assert that Pop isn’t a specific genre of music, but rather the ever-shifting expression of a generation’s joys and anxieties. Pop sheds its skin in every era, wears new names: Rock, Grunge, Rap, EDM. The purists who point to a specific sound (say, late-80s Madonna) and insist, “this is Pop,” miss the point completely. They may as well point to the tomb of Lenin and declare, “this is leadership.”
Some speculate that at the beginning of the 20th century, what we consider Philosophy, the ordered examination of what we know and how to live, also shed its skin. The kids gave it two names: Physics and Psychology.
