I had a college at post grad that did something similar for music. Trained with some genre-specific songs in my country and had it generated a few thousand songs on that genre.

Then they had a LLM do a hierarchical monte carlo voting on the best songs, and made a album with AI generated melody and voice based on the generated lyrics.

Not great, but honestly could pass as real songs.

I know what perl is!

I am also 40.
