It is sort of a blend now. Beats and rhythm tracks are often generated. Vocals are auto-tuned. There's still some humanity in it, but it's not what it used to be.

AI music is generated from the result of training on far more human-made music than any human could ever consume in their lifetime, so there are even more humans involved in its creation.
