Weekly Jams makes playlists of 90% one artist

      For the past month, my weekly jams playlist has been pretty much nothing but one artist.
      See for example this latest one: https://listenbrainz.org/playlist/ba6e3f5d-3b11-4f53-9489-5af7f54eb1c6/

      The daily jams playlists however are working fine.

      I looked at the raw recommendations and while I do have to go to page9+ to see more variety, the variety is there.

      Mayhem suspects that a step in the playlist creation hasn't been applied: limiting the number of times each artist can appear in a playlist.

          This is still a problem for me, and I haven't had a recommendation playlist with any variety in months.

          It turns out I'm not the only user with that problem:
          https://listenbrainz.org/user/silverbluep/recommendations/
          https://listenbrainz.org/user/The4thGoose/recommendations/
          https://listenbrainz.org/user/Capt_Cornflake/recommendations/
          https://listenbrainz.org/user/heliumpallo1/recommendations/
          https://listenbrainz.org/user/JackRyanTaylor/recommendations/
          https://listenbrainz.org/user/jakestanger/recommendations/
          https://listenbrainz.org/user/HumHumXX/recommendations/
          https://listenbrainz.org/user/laughinginfinity/recommendations/
          https://listenbrainz.org/user/greger_jens/recommendations/

          All of these users' recommendations as of writing this also only consists of a single artist King Gizzard and the Lizard Wizard (or > 90%).

          This is the same issue I have, with the same artist, which means the problem could potentially be related to very prolific artists.

          Here is someone with the same issue but with The Beatles:
          https://test.listenbrainz.org/user/freakanth/recommendations/

          This user has 50% Aphex Twins: https://test.listenbrainz.org/user/finical/recommendations/

          These ones have a lot of Radiohead: https://listenbrainz.org/user/hollie_taylor/recommendations/
          https://test.listenbrainz.org/user/gracz/recommendations/

          And finally this one has about 70% of Pink Floyd: https://test.listenbrainz.org/user/williamfrezze/recommendations/

           

          I did look at my raw recommendations which do have some tracks I haven't listened to before, both from KGLW and from other artists. However my recommendation playlist is only composed of tracks that I have listened to before.

          Somehow the recommendation algorithm is doing some overfitting and putting more weight on re-listening to the same songs by that one artist over having some variety or even just listening to songs by that artist that I haven't listened to before.
