I have a Jellyfin environment that I often access remotely via Tailscale and a companion app (Jellyfin for Android, Findroid, Symphonium, etc). Lately I have been wanting to sort my Jellyfin-hosted music library using styles, moods, genres, etc to make some of my smaller albums more visible in my library.

I don't want to sit at my PC for hours sorting through tags for each album/artist/track though. I would prefer if I could tag an album/track/etc with a genre, mood, or style tag while I am browsing my library from a companion app via Tailscale.

Does anyone have a solution that would enable this? Perhaps someone has solved this in an even better way than I have envisioned here.

More generally, how do you all tag your music libraries? Any tips?
