"I think it's the general view of commercial organisations that it's better if the background music is tenth rate, because it's less likely to distract people's attention from what they are there for, which is to spend money. Hence muzak." Not actually true at them horrible plastic Theme Parks, generally speaking, because the music can add much to the ambiance, and it is often used to do just that. HOWEVER, much more likely that some of the choices are made based on how much $$$ is involved. Here's a scenario: "Hello, ASCAP? I'd like a blanket right to play 'Blue Suede Shoes' in the BGM mix for my theme park this year". "OK, how many times will you play it, sir?" "Oh, about 32 million or so. How much would that be?"
