Someone blaring their choice of music in a public space at 90 dB is a “cultural touchstone”?
I don’t drive, I take public transit daily, and am old enough to remember when you would never experience anything like this (even in the heyday of boom boxes in the 80s). So yeah I’m not convinced it’s a “me” problem.
And returning to the point, if you asked someone 30 years ago to turn their music down they would either comply or say something nasty - not physically assault you.
Public music should be celebrated. This is someone sharing a cultural touchstone and y'all just want to be antisocial robots.
