Outside of the joke - I'd say your own definition of prolific undermines you pretty hard there.
While I respect the author for the goal here, I would say he was neither abundantly inventive nor productive.
His inventiveness boiled down to taking an existing concept, and saving some disk space using an already known algorithm. To boot - his method of saving that space rendered the original intent (preventing copywrite of melodies) useless, and was already considered by the original group.
His productivity was a single morning's work, creating a single album, which is just random noise and will never be meaningfully listened to even a single time.
I'm not going to begrudge him the usage in the title, and I think it's a fun weekend project, but I also think it's pretty clearly clickbait (which is fine!).
