I liken this to the smoking debate. Has it ever been proven that secondhand music causes any harm, or is just an annoyance that some killjoys want to use as an excuse to persecute lovers of loud music?
Loving loud music does not give you free license to be a public nuisance. These bass thumpers can take a drive out to the country where nobody is around and blow their brains out on rap/hip-hop at 120 dB for all I care. I shouldn't have to hear it when I'm sitting in my house eating lunch.
I am frequently wakened at night with my windows rattling from "secondhand music" (and Harley pipes, thuough less often). They are anathema and a bane on humankind.
Man is that flawed logic. I don't give a crap what kind of music anyone listens to, nor do I care how loud it is. But they should play it where others are not forced to listen.
As a matter of fact, the manner in which most of these RichardHeads play the music is not so much because they like it loud, but because they enjoy annoying as many people as possible.
Example (happens very frequently, BTW): It is 98 degrees, the middle of summer in central Florida. Long lines of traffic on black asphalt roads backed up at intersections. 18 year old kid is sitting next to me in a new or nearly new car with all four windows down and playing a $2500 system at 150 decibels. The heat is stomach turning but he won't roll up his windows and turn on his A/C. Yeah, he's not doing it to bother anyone, he just happens to be a connoisseur of loud music. BS. AFAIAC I should have the legal right to pull out a baseball bat and smash his windshield. I just happen to be a connoisseur of cracked glass.
Doesn't matter as it's in the part of the constitution that says you have the right never to be offended or annoyed.
I find it annoying when I'm in my old geezer cranky mood but it's not like it's going to ruin my day and while it's hard to remember that far back I think it's pretty safe to say that when I was a teenager I did some stuff that probably annoyed grown-ups.
In fact I suspect that had the technology existed back then I probably would have been booming the Naughty Lady of Shady Lane.
