mjourdan If the goal is to have recommendations, there is not only favourites to take into account, but also playlists and listening history.
listenings has its own forum thread. But what do you suggest about playlist ? I'm not aware of listenbrainz using user playlists to generate recommendation but it sound like a good idea. Probably better to speak about this with them tho'
mjourdan How is the LB identity created and shared? Do people have to explicitly create an account in LB, or is a token automatically generated by LB clients? When/where shall we ask for this token?
An account on LB is needed. The token will be set on the LB addon page (to centralize LB stuf in one place and avoid multiples settings)
