Spotify Tools

Spotify Tools lets you set listening goals for artists, albums, and tracks you want to hear more of. It syncs with your Spotify listening history, tracks your progress, and generates playlists of exactly the music you still want to listen to. You also get detailed statistics about your listening habits.

Unfortunately, Spotify no longer verifies small apps from individual developers, so it is not publicly accessible. If you would like to try it, contact me with your email, and I can give you access.
