How much does the BBC pay the prs per song?

The BBC does not pay the PRS on a per song basis. For radio stations the BBC pay a per minute rate, rather than for individual songs, which is then distributed to the creators via the PRS quarterly payment system - if the length of a particular piece is not known it is calculated at 3 minutes and 1 second for payment calculations. The rate varies for different stations and between national/local radio stations and terrestrial TV/satellite TV stations. There is also a blanket licence which covers BBC usage across TV, Radio and online for use of music in jingles promotions etc.
