Track and organize releases you want to listen, listened or liked (aka. digged).
Stumbled upon something interesting on Spotify, Discogs, Bandcamp, Mixcloud or other? Add it to Want to Listen and don't worry about forgetting it.
Share and discuss your digs with friends. See your friends' activity as well.
After all, fellow human beings are the best recommendation systems.
Put another way, Digs is like Goodreads®, but for music.
