What's so surprising about a bunch of commuters in a metro station on the way to work being too busy, too preoccupied and too habituated to jump the rails for some serious, long-form music, no matter how high- quality? Any marketing person could have predicted exactly what happened, let alone any busker…
Similarly, I don't see any evidence that an average crowd or the average person values random beauty much at all. How often have you ever seen a freeway traffic jam, or even a single pulled-over vehicle, during a spectacular sunset, or any other jaw-dropping display of light on landscape as seen from the road? Nothing's less important than the "task at hand".
What's more of a cliche than "Stop and smell the roses!" or that the Artistic Life (which is not renowned for being an enviable one) is about noticing the beauty that everyone else misses?
