Who gives them the right to play music all day when the only ones who will benefit from it are the musicians the music companies and all the agents and so on associated with the musicians.
I think it is called entertainment.If the BBC had to choose not to cover the release of new films,and other media,on the basis that they are produced for commercial reasons they would have great difficulty making programmes,enev news,as they would be unable to refer to things that might interest their audience.
