YouTube has secured an agreement with the UK societies that collect royalties for 50,000 composers, songwriters and publishers to legitimise the use of recorded music on Google’s popular video-sharing website.

The agreement to license 10m pieces of music to YouTube – in return for a flat fee which has not been disclosed – is the first of its kind, said Steve Porter, chief executive of the MCPS-PRS Alliance. “This is the first fully formed agreement,” he said, although some US collecting societies had reached interim arrangements with YouTube.
