Turning off the music in Nigeria

In protest at the claimed non-payment of royalties by radio stations, Nigerian artists called for today to be a "no music day" on Nigerian radio.

Not quite sure I'm following the logic - if Nigerian radio stations don't pay to play music, why are they happy to take part in an event to draw attention to the problem rather than simply paying?

And since many stations just took the opportunity to play non-local music, the whole thing sounds like a bit of a own goal. Not that the foreign artists would have got any royalties, either. Perhaps Feargal Sharkey could go to Nigeria to help a music industry with actual problems? I'm sure we could spare him.
