My wife's Mum owns a hairdressers salon and listens to Magic Radio during the day. She has already paid around £60 for something from a company called PRS but has now received a bill out of the blue from something called PPL which is another £70. I don't understand how this all works. Does she need to pay them both or can she just tell them to get lost? It seems like quite a lot of money to pay just to listen to an oldies music station.
