I wonder if these battles will shake loose the circuit split on de minimis exceptions to music samples (see https://lawreview.richmond.edu/2022/06/10/a-music-industry-circuit-split-the-de-minimis-exception-in-digital-sampling/).

Currently, it is absolutely not "cut and dried" whether the use of any given sample should be permitted. Most musicians are erring on the side of "clear everything," but does an AI-generated "simulacrum" qualify as "sampling"?

What's on trial here is basically "what characteristic(s) of an artist's work do they own?" If you write a song, you can "own" whatever is written down (melody, lyrics, etc.) If you perform a song, you can own the performance (recordings thereof, etc.) Things start to get pretty vague when we start talking about "I own the sound of my voice."

I think it's accepted that it's legal for an impersonator to make a living doing TikToks pretending to be Tom Cruise. Tom Cruise can't really sue them saying "he sounds like me." But is it different if a computer does it? It may very well be.

It's going to be a pretty rough few years in copyright litigation. Buckle up.
