If shops play muzak or whatever name you give to the aural wallpaper that assaults your mind and or intelligence then I don't go in.
However, how do I avoid the aural shite that the BBC play behind serious announcements about upcoming programmes on the radio. I wake up to BBC Radio Four and at the end of the day bed down to the same station. Between programmes we get announcements of programmes (and to non UK folks I should say Radio Four is mostly a serious station carrying serious news and documentary programmes)but inevitably while the announcement/trailer is being made there are irritating percussion like noises, random piano notes repeated over and over or something else equally so annoying and distracting that you don't get the message. Who the hell is responsible for this.
Wild life / nature TV programmes are also subject to the same insulting sound tracks (noise). The silence or sound of nature isn't enough. Excellent programmes are ruined by the fact that I keep having to hit the mute button every few minutes.
What is the study that makes people think that natural sound isn't good enough?
