What I haven't seen done well by these generative AI's so far is structure (having a chorus, a verse, a bridge, ...) and harmonic movement/progressions (except for maybe a V-I or I - VI - ii - V) And those two be things are exactly what makes a song interesting and non-repetitive.

OpenAI's jukebox -- now 3 years old -- is creative and non-repetitive. Witness, for instance, its jam on Uptown Funk here:

Or the changes shortly after 1:15, 2:15 and 2:40 in these extensions of Take On Me:

Okay but here it still seems like it's just taking over snippets. It did not come up with the progression.

If inventing new chord progressions is one of the requirements for musical creativity then neither Handel nor Paul Simon would qualify.
