I feel like a lot of artists do this or try to do this. Take credit for music or lyrics that others have helped with. This probably happeneds more then we know about. They just made an entire Disney movie on it. Coco. It basically was about 2 singers and the one killed the other so no one would know he made and wrote all the lyrics and music that the one guy stole. I mean any way you look at it it's not right. The guy does serve and pay out and then some for what he has done to his friend.
