Any chance Jellyfin and Finamp have a music playlist and mix building feature?
Plex has this with Plexamp but I have not had a chance to look into jellyfin to see if a plugin offers something similar.
I hate building playlists, Plex offers a few different options like sonic sage, sonic adventure, artist mix builder, and automatic mixes based on past listening history.
Found the DHD, covered by some shrubs.
