You can still set up local login for Plex to avoid their auth on your own network or list of allowed IPs. It's not 100% what people want, but it's something.
Other than a few UX bugs I haven't had any real issues, so I'm happy with it.

* Similar artists, tracks, etc * Auto-playing similar after listening to an album * "sonically similar" tracks/artists - not just some arbitrary decision that some artist is in the same genre, but that the songs have similar sonic profiles * Artist/track radio based on all of the above * "library radio": smart shuffling * artist mix builder: creates playlists based on some artists that you choose (and includes tracks from similar artists automatically)
I have too much music to know what I want to listen to all of the time and I don't want to sit there carefully curating playlists and trying to discover things: Basically, I want a system that's smarter than I am to tell me what to listen to (but with my own music that I own, obviously)
In navidrome I view the random albums page until I find something I want to listen to. The only algo that I've found to bear fruit is youtube's recommendations, occasionally. I mostly just listen to music on there while working and occasionally it just drops great albums.
As a general note, I find it fascinating that it could be something lagging so far behind, for me playing music is either via artist (maybe, as a secondary sort, album) or via genre, rarely anything else.
