I believe we've already crossed the quality threshold for being equal to or "better" (subjective) than human.

For EDM, check out the AI artist "Vibfy". Especially the song "I Hear You" as it has the best mastering so far. The melody and vocals of all the songs are fire, but in some of the earlier songs the mastering is sub-par with strange volume changes and muddy beats.

There is an AI folk band called "We're all f*cked" that is incredibly good and indistinguishable from actual humans.
