Kanye West is allowed to “rip-off” other songs as he often does by taking elements from existing songs and adapting them for his own use. This is due to the concept of copyright law, which permits the transformation or adaptation of copyrighted material for any number of uses, as long as the original source is credited. The concept is called “transformative works” and has been largely accepted by the music industry as a way to create new music without infringing on existing copyright. This means that Kanye West is allowed to take existing songs and adapt them for his own work, as long as he credits the original artist.
