As someone who doesn't have knowledge or taste in music, I do wonder how does music work in regards to the works they're associated.
For example I've seen games been taken out for not renewing musical rights. Do movies also have that? Also in terms of dances can they be owned? If so Michael Jackson must have had to get something from the thriller dance that I think it's still being homage until today.
In the end it's like they say, nothing is original, new works always take something from someplace and somewhere else, it's just the level of blatantness varies.
