This is more closer to actually creating rather than generating music. However this cannot be done with a text prompt, which the comment above claimed, is expressive enough.

Actually having an "autotune" AI that turns out-of-key poor singing into a beautiful melody while keeping the voice timbre, would be not bad.

Well then I have news for you... That's what Suno is. You can generate from simple text prompt, you can describe timings and chord progressions and song structure. You can get very detailed, even providing recordings

Yes the barrier for entry is low, but there is a very high ceiling as well
