We use a shallow neural network to learn about songs from playlists we scraped from Spotify, but to actually build the playlist we use some straightforward vector math.
Rarer songs/genres do tend to be all over the map, and certain super popular songs seem to show up all the time. We are still messing with the training, pulling in more playlists, and working on the playlist algorithm. Every training run produces better results!
From the comments, it does appear that we set the threshold for how frequently a song must appear to be included a little low based on the sparsity of our training data.
