The artists are all unhappy with MSCK because of the corruption and meagre earnings of ksh 1,200 per year....for a big budget campaign team like azimio and Kenya kwanza going to the same society would be termed as exploitationTrue. And one fee paid to the copyright society allows the payer to play the music of ALL the musicians under the society's umbrella. I think (and this is pure speculation, not fact!) the difference comes when a campaign wants to adopt a song as their theme song.
