Well a couple of things.

In the United States:


1. They force restaurants to shut down. $40,000 fine for 4 songs.

69 Taps in Medina is hardly the first local bar or restaurant to be on the receiving end of a lawsuit from BMI or the American Society of Composers, Authors and Publishers (ASCAP), the two largest Performance Rights Organizations, or copyright collectives, in the country. Every year, bars, grills and taverns across the country find themselves ordered to pay tens of thousands of dollars to the non-profit behemoths for crimes ranging from playing Bob Dylan on a jukebox to allowing a group of amateur rockers cover John Fogerty. In August of 2011, for example, Fosters American Grille in Raleigh, North Carolina was ordered to pay BMI $30,450 for playing four songs without a license and another $10,700 in attorneys’ fees. The restaurant shuttered that same month.

2. I guess when the owner of a website like this says no cover songs they must have a reason and mean it or they wouldn't have put it up in the first place.
