Did you know that there are 4 million unheard tracks on Spotify? That is around 20% of their catalog. This is why Lane Jordan put together a service called Forgotify. He worked with this project with his friends J. Hausmann and Nate Gagnon. Forgotify has created a database to crawl Spotify’s API for songs that have a play count of zero. After the song has been played once, it disappears from the website but lives on in Spotify unlikely to be found again. Many of Spotify’s undiscovered tracks are older songs.
