Yes, it's not "creative" so shouldn't be protected by copyright, but still points at a legal problem; we're entering a time in which AI can generate human-level music with as much or as little user input as the user wants, so how can we determine who owns the copyrights if we don't know how much "creativity" was actually involved? (And AI music generation is far easier than AI writing fiction or drawing, though AI is certainly going to come for those too.) Perhaps there will be only two ways to handle it: 1) Case by case when people file lawsuits or 2) no more copyrightable music? No idea, but we're going to have to figure it out soon...
