You can pin your recording jam, recommend tracks to users, view statistics in your listens, create and listen to playlists. We are actively working on adding various type of recommendations for users and also intend to add more music discovery features in future.
(- a ListenBrainz Dev)
I think that the my other comment comparing Digs to Last.fm (https://news.ycombinator.com/item?id=32552617), applies pretty much for a comparison with ListenBrainz as well.
While they have some overlap (i.e recommend tracking users, statistics), they do differ in the fact that the one defines "listen" as "listen (new or repeated) of a track/album/artist", while the other defines "listen" as "first-time listen of a release".
Also, the other main focus of Digs is providing a way to organize your "Want to Listen" list (with tags, notes and more on the way), as a means to stay on top of all the music you found interesting at some point. The problem I had, specifically, was that I had "Queues" of things I like to hear in the future (albums, mixes, etc.) in 3 or 4 different sites: YouTube, Soundcloud, Mixcloud, Discogs, Spotify. So I wanted to have a single way to organize all these (that's why Digs knows how to parse URLs from these services) and share them with friends.
All in all, I love ListenBrainz and I believe there is room for both sites in this world, since they tackle slightly different needs.
