I'm perfectly happy around very loud music when I go to a concert, but I don't want it while I shop. And, luckily, when I shop online, I don't have to put up it, so it's no skin off my nose to avoid shops that are noisym (see also "have TV screens every two meters flickering wildly", "stink of cheap fried food", etc).
One of the many reasons I couldn't care less about the "demise" of the high street ("justice being served" would be a better description) is that I have money to spend and shops, which then bleat about unfair competition, make actually spending it extremely unpleasant. Many of them are seemingly setting up their shops to appeal to teenagers with limited funds, rather than older prospective customers who can actually afford their merchandise. There was a time when I had to put up with it in order to buy stuff. Now I don't.
It isn't my circus so I don't particularly feel an obligation to advise on monkey-keeping practices. But clearly, to judge from the precarious financial position of high street retailers, I'm hardly the only person who doesn't like their current offering.
