The AI songs always sound like the point it a rappers career where they've made all the good music they can and have nothing else interesting to rap about.
A huge point because the best artists push the pen to reflect their life and circumstance therefore these AIs can only be weaker retreads of paths they've already taken. Veer too far from that lane and it sounds inauthentic.
The next step with this once they master the fake vocals, cadence and pitch will be feeding in their lives work, personality profile etc... to create a synthetic human mind that is up on current times and reacts as they would in the moment.
Simulacra and simulation aka
a copy without an original.
This is very impressive and a nice use of the medium tho:
