Secondly, what percentage of elevators even play music these days?
Pretty much every elevator I've been in for the last ten years. I note it mentally because spirit of the music is always at odds with the messages on the display screens.
I think the only elevators where I haven't heard music recently are in residential buildings.
huh... no shit. I think I've encountered maybe 2 or 3 elevators that play music in my life, and I'm a middle-aged guy living and working in a major metropolitan area where most non-residential, and many residential buildings have elevators.
