It's a fun concept, and maybe will be useful in some weird edge case of a lawsuit, but no. Most recent music infringement lawsuits seem to argue that some combination of the sound design, groove, rhythms, chord progressions, melody or reduced melody, structure, and lyrics wind up giving a song the same "feel" as a prior song, and that's the basis of the copyright infringement. Then pseudoscientific experts come in and pick and choose common musical elements that both the songs share to attempt to justify the claim, oftentimes wrongfully taking credit for inventing genre-wide defining musical elements. Adam Neely did a good job touching on this in his recent analysis of the Dua Lipa Levitating lawsuit [1].
An AI generated song machine would have to nail a lot more elements than just the melody notes to properly stop music copyright cases. In my view, a more interesting project that might be more effective in defusing lawsuits would be to try to catalog all of the musical tropes that define genres, then attempting to detect how common they are in that genre. In an ideal world, maybe this would be able to drive a metric of how similar specific two songs are vs. picking any two songs in that genre at random.

He most certainly did not. Of all the different takes out there, his is very weak.

There is a very good reason: as he mentions, the chords diversity use in pop songwriting is typically so poor that based only on that, the amount of things considered plagiarism would thus be ridiculous. If the similarities affect almost all dimensions (style, arrangement, rhythm, melody, ...) to the point of being "essentially the same", then it's exactly what people would want the law to exist for.

I think Adam Neely did a good job explaining what infringement lawsuits mean in the context of popular music production. Whether or not you agree with the strength of his case on this particular lawsuit, well that's not quite the point I was trying to make here. Still, what do you consider to be a strong take on this case?
