copyrights. There are some people stealing royalties from artists by putting their music on digitalplatforms without informing them and when getting contacted by the artist or their management to give the stolen money back or transfering the music on their name, they refuse and block them. It leads them to the justice, which make the music getting removed on the platforms until that the problems are solved and the artist later putting it on his name. You will notice that some Congolese artists have or had two versions of the same album on Deezer (some even three).
