When it gets to me I just seek out the manager and demand that they turn it down. One of them told me that most people enjoy the "music" which was the wrong thing to say to me! I told him that it has the opposite effect on me, and that it makes me want to break things and hurt someone." He said, "Well, we don't want that" and he turned it almost off.
I don't go to a store to be entertained, and I highly resent being forced to listen to someone else's poor taste in music. That crap they play now sounds like a hog caught in a barbed wire fence. Caterwalling is the word.It makes my nerves bleed.
