Yeah, I'm really appreciating that this doesn't have any idea of what "popular" means, so that its recommendations are just based on similarity, as opposed to Spotify's algorithms, which typically seems to use other user's listening habits to influence the same.
It's not always great, though. I plugged in Debris by Lorn, which is a very somber, but still melody-driven song. All of Maroofy's recommendations are just noise scapes or spooky stock library effects: https://www.youtube.com/watch?v=mBCsdIQi7uk
IMO my idea for making something like this really cool is to give the user more explainability (why are these two songs similar? according to which factors?), and then more control over search results (brainstorming here, but stuff like an obscurity slider, importance of beat similarity slider, etc.). You can try to extract explainable factors from your embeddings with something like NMF.
(PS—I like the esoteric results. This is cool, good job.)
