Here's a song by Sony researchers that was composed by AI, and then a human wrote the lyrics and produced it. The intent was to create a Beatles sound, and I think they did quite well. https://youtu.be/LSHZ_b05W7o
Depending on the audience, particularly their level of attention or focus on the music, you can probably get away with playing a completely un-human pop song that people will like.
I find the possibilities here very interesting, but I also greatly fear that this will become the norm the same way that nearly every modern song uses autotune.
Humans are really good at vocals, and it would thus be very hard to replace, eg. making a speech synthesis model sing well. Melodies however are more mathematical and could possibly be generated by a computer.
Add some Grover-like text for the lyrics (https://grover.allenai.org/), and you're most of the way there. Then use a deepfake singer ( https://youtu.be/k3qJOPrJOQ4 ), and you're most of the way to done.
