@alfabravoteam @AlisonCreekside The AI and its owners probably signed no licence agreements so I doubt licenses of any kind have any bearing on the debate.

"derived" in the sense of "derived work" has a specific meaning, so if something was Enter Sandman derived it wouldn't matter whether it was generated by an algorithm (and calling it 'AI' is misleading IMHO), or by a human. It would be subject to copyright law and the Enter Sandman rights owner would own some of the rights.
