This is neat! It's cool how powerful Spotify's API is.

I built Amplitude [1], which uses Spotify's recommendations API to create artist based discovery playlists, if you need more new music than Discover Weekly provides and also Rediscover [2], to save your discover weekly playlists so you don't lose songs.
