I can usually tune out most of the "music" but RAP or really loud noise sends me running. If they can do without my dollars, so much the better.

My worst Muzak experience was at a jobsite in the early 70s. The owner had been sold a bill of goods. Every day we were motivated in the AM by "Hi Ho Hi Ho, It's Off To Work We Go" and after lunch by the Can CAn from Orpheus In The Underworld. Drove me nuts!
