Now and then, it's slightly off-putting when I hear current music that I don't recognize or don't like in a store. It's never more than mildly irksome, though, as I can't reasonably expect a store to anticipate my arrival and play only my favorite music while I shop.
Also, more often than not, I hear stores play music from 20 to 50 years ago that I enjoy. Thus, I really can't complain, because even by the luck of the draw, I've usually gotten my way.
