Then you could claim legal ownership of the music, but not the lyrics.

The issues with AI and copyright is that AI is not a legal entity (yet) so cannot be granted a copyright. As a result, the work is functionally in the public domain.

That could include inputting chords into BiaB, selecting a style, then adding other tracks via guitar, bass, keys, etc. Or what if all of the instrumentation was done "organically"? Wouldn't these scenarios indicate a a significant amount of human authorship?
Not as far as the lyrics are concerned.

Think of it this way: imagine there's a public domain song, such as "Twinkle, Twinkle, Little Star". Anyone can use the melody.

Now, imagine that someone wrote alternate lyrics to the song:

   Twinkle, twinkle, little bat!
   How I wonder what you're at!
   Up above the world you fly,
   Like a teatray in the sky.


The author of the new lyrics owns those new lyrics, and other people can't use the public domain melody with the new lyrics without infringing on their copyright.

But the author does not now own the melody. People can continue using the public domain melody with the public domain words. They are free to write their own new lyrics that use the public domain melody, or new melody to the public domain lyrics.

The only thing that gets copyrighted is the new material that was created.

Well said David.
