In my experience it is function of how a society values personal space and courtesy.

You do find a lot of social music in high density environments such as in found in global south or in America cities where personal space is not a much of a choice , while Taiwan (or Japan or Korea) is high density too the extreme courteous culture makes them different.

It is also different in what makes public music, it is not necessarily someone playing their favorite songs , in India for example things like religious events or weddings or funerals people tolerate and even expect public music but typically don’t accept say a guy with a boom box .

It is very different way of growing up and living if you have to no choice but hear neighbors fighting or having sex , public music wouldn’t feel so offensive when you hear a lot things you prefer not to daily.
