Songstack is a Spotify-integrated music discovery app that gives control back to the listener.
The app asks you to swipe to like or dislike every song that you hear, and in turn future recommendations will become more accurate to your taste.
Furthermore, you are able to tune any of your Stacks (by their acousticness, danceability etc.) in order to have even more control over what kind of songs you encounter.
