Over 150 British music stars have written to the PM warning that payments from streaming songs to writers and performers are so low as to be critical. Paul McCartney, Kate Bush and members of the Who, Led Zeppelin, Pink Floyd, Oasis, Dire Straits, the Charlatans, Coldplay, the Smiths, the Cure, Fleetwood Mac, Monty Python, Fleetwood Mac and the Spice Girls want a minor change to the 1988 Copyright, Designs and Patents Act to redress this. They point out: "Songwriters earn 50% of radio revenues, but only 15% in streaming. We believe that in a truly free market the song will achieve greater value." The letter was put together by the MU and the Ivors Academy in partnership with Broken Record led by songwriter Tom Gray.
