Just a thought.......
Apparently, even music performed "live" is covered by the PRS demands for payment.
Therefore, at a folk club, where I play "traditional" songs.....who gets the royalty? There is no known author of the work.

I've also penned a few ditties myself, and have heard others singing them (which gave me an immense sense of pride) but never a penny expected from or granted by the PRS.
The way I see it the PRS just collect a "tax" which is paid out to the big names in music.
To quote the words of a friend's song " The rich get rich, and the poor grow many" (oops....I suppose i should pay him a royalty for that!)
Once music is on the airwaves or on a CD.....it is already "in public" and therefore nobody should pay another penny, unless a much fairer system of distribution is invented.

Rant over......
