That is a great idea! Measuring distance between embeddings has always been a cool concept (ex. If I have a vector that represents the word "king" and from it subtract the vector that represents "man" then add the vector that represents "woman" it will approximately equal the vector for "queen") and it's awesome to see the same concept applied to music.

Most other services try to find matches by seeing what other songs the people who like the searched song like, and finding trends amongst those. This site finds songs with similar sounds and rhythms by looking in the vector space. Awesome! Congrats on the finished site!
