TLDR: I ended up installing Chora, pictured in the thumbnail, which is open-source and works pretty well on TV (and on mobile). Navigation works with remote, and I was able to connect to my music collection quickly. I moved the music collection to Navidrome, and I have noticed that it generally loads and searches my library faster than Jellyfin. It does not have a continuous play/instant playlist (like for example, Tempus on mobile), but otherwise checks most of the boxes.
Original Post:
I have a great music library on my homelab, but I hardly ever listen to it because I mostly listen to music on my TV.
I occasionally use the Jellyfin app, which is the best player I've found for TV, but it is not really built for audio and is cumbersome for searching, on-the-fly playlist, and continuous play.
Other apps I've tried are either worse in terms of features, or an absolute labyrinth to navigate with a remote. Most apps are designed for mobile and are somewhat to completely broken on TV, if they run at all.
I don't mind if the app is not free as long as it works well enough for my family to use it, and it connects to the server. I don't mind migrating my library to another service to get it working well on the TV.
Has anyone found an actually good Android TV app for hosted music?
FinAmp is a fantastic JellyFin music player, and even supports offline downloads for on the road. Sadly the interface isn't really AndroidTV-friendly, but it works great on android touch screens, iOS, linux, and macOS (probably Windows too, but I'll never know).
I'm looking for a good AndroidTV player as well, because the official JellyFin app doesn't background well. We like to play music in parallel with a screensaver or fireplace app, but JellyFin pauses after about a minute when hackgrounded.
