Your equivalent ilk of decades past complained about "kids these days" and their boomboxes in public in basically the same way you're doing now.

It's not one guy with a boombox now, it's 7 people with TikTok open on their phones.

It's not kids - if it was then sure, I could write this off as "kids these days". But it's all sorts, all ages, all cultures. Obviously some folks always wanted to do this.
