First of all, thank you so much for being part of Jellyfin, I paid the Plex Pass lifetime thing a few years ago, and Plex has turned into the exact opposite of what I want. I'm going all-in into Jellyfin.

But regarding music:

I listen to music every day on my car, if I can't use Jellyfin with Android auto, I'll have to chose another app for the job. I've found it to be really convenient and safer.

Edit: If there was an equally convenient FOSS alternative to Android Auto I would switch to it in a heartbeat.
