That seems like good advice for professionals, but I'm wondering if it's going to hold up with new ways of distribution.

Would distributing a generative model that can sometimes generate such music would also be considered illegal? Will it actually stop people from doing it in practice?

Would it be illegal to share seeds and prompts?

Though these alternative methods, you could have a lot of people listening to music that's never distributed as audio or video files. And if there's an API for it, games could use such generated music via a plugin.

And then I suppose people start sharing on YouTube, and we see how good their copyright violation detection actually is.
