I guess this isn't what you want to hear... but like others here I'd recommend you organise and tag your music properly. Then software like Jellyfin or Navidrome should work properly.
I use MusicBrainz Picard and have seen people recommend https://beets.io/, which I still haven't looked into.
+1 for Finamp beta. It is great and under active development.
You can get the latest version here: https://github.com/jmshrv/finamp/releases/tag/0.9.11-beta
Mmmm, did you try the latest beta or the stable version?
The stable version is quite outdated and download doesn't work great there. With the beta version (0.9.11) I'm able to download full albums, full artists or individual songs. I'm very happy with it. I'd recommend you give it another a try if you have time.
If you're interested in an alternative to Gelli, check Finamp (https://github.com/jmshrv/finamp): it is a Jellyfin client for Android that can also download music to play offline. Try the latest beta version, it is way ahead the stable version and works perfectly for me as a daily driver.
Glad that I could help. If you need help with setting the custom DNS or choosing which domains to block feel free to ask me here.
I'm not the person you replied to, but I think my experience could be relevant.
I have a MiBox TV S 4K, which as far as I know runs pretty pure AndroidTV (but I might be wrong). This is still going to try to connect to Google and Xiaomi servers for tracking and ads... but I have set up a custom DNS blocking trackers and ads.
I found this Reddit post and followed the instructions to change the DNS server on the MiBox to NextDNS, where I could later activate relevant blocklists (SmartTV, Xiaomi, Google). I also perform monitoring of the domains the MiBox connects to and have blocked a couple manually.
Finally, for AndroidTV forget about NewPipe and use SmartTube. It's the same idea, but optimised for the AndroidTV experience where you have a remote and not a touchscreen.
I'm going to paste here the comment I wrote on another post about this same issue:
Organic Maps and OsmAnd are not adding ads during navigation. Nor "promoted pins". Nor ads when browsing the map. Nor tracking your every move.
Seriously, give them a try. And remember that, if the maps are lacking information, you are free (and encouraged) to improve them on OpenStreetMap.
Open Tracks allows exporting in either KMZ (default), KML or GPX format. Go to Settings, tap on "Import and Export" and there look, towards the end, for the entry "Export/sharing file format".
MP3Tag sounds cool, but there's no Linux version it seems :(
Good to know. Thanks. I have my music in my server, which runs Jellyfin and Navidrome on Docker...
Would it make sense to install it on Docker too or would it be OK install it on my computer and then have it check the music oh my server over NFS?
