You mentioned that "the biggest hold up is getting enough properly trained data, tagged appropriately, in order to let the models train correctly." I think using SNES music as training data is a viable way of getting hundreds of songs' worth of training data in a fairly automated fashion. (I'd estimate that each game has 10 to 80 songs which can be used for training, I have 5 to 10 games of OSTs already downloaded, and each song is only 64 kilobytes and takes minimal disk space before rendering to WAV.)
