Are you asking about music, or audiobooks specifically? I haven’t tinkered with audiobooks so am not sure if that’s handled differently…
For music I’ve been using Jellyfin as the server. On Android have tried a bunch of different apps, substreamer and Symfonium are the better apps. But I also like Fintunes, Jellify, and Resonus.
Fun fact: You can use most OpenSubsonic / Subsonic compatible apps with Jellyfin once you add the Subfin plugin (https://github.com/williamkray/subfin-plugin).


I’m definitely in the thinking with others that keep admin/privileged and normal users separate. I kind of look at it as a way to minimize fallout from any unexpected security compromises. Will always do my best to prevent/avoid that, but if it happens it better happen on a non-privileged account.
A bit, but I don’t find that to be too cumbersome. The initial setup period yeah, you’re constantly jumping into admin mode, but once things are configured and settled down you hopefully don’t need to jump into admin mode often.
That’s a fair question and it depends on the service(s) really. I don’t know what the general consensus is on that but I’d say that other admins should have their own separate admin account and user account (e.g. call it “joe” and “joe_admin” or whatever). Sharing credentials, especially admin credentials, seems like its own security risk. But I also get that sometimes it’s simply not possible to maintain multiple admin accounts and you just have to do the best you can.
