Diane: As a lawyer, I’d say the rule of thumb is that copyright only protects works with a human author. If the AI just spits out a chord progression with no creative input from a person, it’s probably not protectable, so anyone could use it. But if a human tweaks, arranges, or adds to it, that new version could get protection. The tricky part is determining where the human touch ends and the machine starts—courts are still figuring that out. So, in practice, most people treat AI‑generated material as free unless there’s a clear human contribution that adds originality.
