I am not a copyright expert but surely, even those without legal brains can clearly see that a legal case can spring out of an artiste performing the songs of another artiste, without express permission or cover royalties having been paid—especially at concerts where he has taken money from the organizers to perform.
Since this is happening in Ghana, no one may get sued and also, because it is Shatta Wale doing it to Samini’s songs, any attempt by the latter to seek redress in court or to protect his intellectual property from such infringement would possibly be met with all manner of fans’ attack.
But the fact remains that; in law and even when perched against common sense, you cannot take money from an event organizer to perform—and while out there, just decide to perform the song(s) of another artiste without permission or without the event organisers paying the artiste the required fees for the cover. That is a clear violation of the other artiste’s copyright and a slap in the face of the copyright legislation.
Interestingly, Shatta Wale has done this twice or so and no one including MUSIGA or the various bodies which seek to protect the works of Ghanaian artistes has called him to order—or brought to his attention that his actions are in breach of the law.
