Okay, so those are twizzles that "don't move at all." I mean, they seriously looked like spins because they were done in place.
You can't copyright AI music so there will never be rights issues with it.
If courts decide that Generative AI violates copyrights, that would be different but I don't think they will. That is because, if implemented correctly, Generative AI doesn't copy the music from its source and store it locally to refer to. Instead, it "listens" to it and stores notations about it.
It's basically the same as you listening to a bunch of songs and making notes about them as you are listening. Of course, computers do this a million times faster than we do and they can read their "notes" (mathematical notations) much faster too.
