I get the feeling that at some point the muzak groups did some kind of study that shows shoppers are more likely to frequent a place if they play one slightly obscure song they really like. Which will lead to places like a convenience store playing a string of obscure tracks from a large variety of genre's.

Or at least that's how I explain my local store playing a country song into some obscure song I love from 20+ years ago, into some modernish pop song.

Maybe some place has furthered this with recognition software, but I don't interact with much social media and still have noticed this.
