The whole idea of Copyrights in Music is fucking retarded
For most of our fucking history we all just copied what was tradition in the culture we were in, even during the 1500-1900 where people view that as an era of innovation it was actually Europeans evolving the technique of the post Roman Tradition , the main focus was advancing Technique rather than Innovation , Innovation came from copying(Just like how Led Zeppelin is both innovative and a literal cover band)
Imagine how backwards music would be if cavemen had copyright laws , where kronk gets bashed in the head because he clicked his rocks in a way that sounded kinda similar to how Grug did it
