I'm really curious how much effort there was in building up the data set - before, training the model before you got to "music"

Reading the steps feels like 9 months to a year before you got to credible music.

What kept you going in the belief this would work. I can think of 20 reasons why this shouldn't work - hence its "surprising" that it does. Its quite easily something you could have worked on for 5 years with no results.

reading your background - it also sounds like your time would be tightly constrained hence figuring out where to deploy it - you need to have some conviction you'll have success
