Forgotify

It's old news at this point but new to me. Forgotify is an API service that mines the depths of Spotify to find songs with zero play counts (or partial play counts) and surfaces them one-by-one for you to experience. Though my time with it thus far has been brief, the offerings have been good! It's a solid reminder that just because it's good doesn't mean it's been heard. An issue a lot of artists deal with.

If you're into Forgotify, there's also No Likes Yet for Instagram, The Long Tail for unpopular songs from your favorite artist and PetitTube for YouTube.
