Very interesting. I love the "corpses" reference. Very creative.

Very cool, I put in a project I've been toying with converting sheet music to MusicXML, surprisingly dismal lmao.

This actually looked excellent, except it seems in my case to have hallucinated much of the information and links - every "receipt" I clicked on resulted in a 404.

But a website that can tell you if your business idea has been done before, and the reasons the previous companies that tried went out of business... that's actually a great idea. Maybe I just got unlucky with my search.
