You aren't being that facetious. My father was a restaurant manager in the 70s and he had to catalogue every record he had, how many times each song was played, and then cut a check to the appropriate record companies to avoid getting sued by them. This wasn't a chain restaurant or anything either, just a small little one. They are really assholes about playing your own music, luckily you are allowed to play internet, terrestrial, and satellite radio for free (they have yet to impose a fee on that I guess) and Pandora counts as internet radio so it makes a great solution for businesses.
Actually now that I think of it, Pandora should offer a business or premium plan. Because businesses have to display the name of the song/artist playing when they play the radio, Pandora should offer a simple, ad-free song title display that businesses can use when playing their songs. There's some revenue! Yay! Stay in existence please!
