Yeah I have that one as well but its pretty spartan. To be honest, I haven't even logged in like a year. I've been using last.fm since 2005, listenbrainz since a few months ago but it had a thing that imported all my scrobbles from last.fm. Listenbrainz (and musicbrainz) is a cool project and I'm looking forward to what they come up with in the future. Last.fm is great as well, especially since they got back to independent recently. Both are cool in their own ways, so I'm gonna stick to them, just wished their recommend system was better.
