Musicbrainz Picard + Emby/Jellyfin is a great combo. Emby servers double as navidrome servers so you can use myriad apps to listen.

Archiving/preservation is separate to consuming the content.

Worst of all, just setting up a tiling environment is a nightmare. You have to configure the actual compositor/WM, which tools you want to use with it (bar, launcher, screenshot tool, notifications, screenlocker, etc) and configure all those too, ideally with some basic theming to make them look coherent. But inevitably you end up with missing functionality especially in the modern area where an app might be sandboxed or expecting all xdg-portals to be implemented, which most compositors don’t do.

Khronkite is worth checking out in relation to this point. It requires minimal setup (keybinds + choosing tiling layout) so it’s a good introduction to tiling WMs. I’m guessing more experienced users would prefer more control but I like it just fine.

From my limited research it looks as though the Punkt mp02 is the best bet for a private dumbphone. It does use a propriety OS but at least it supports Signal.

100% It reminds me of the piece of shit kid from The Strain. Even having me hate them is an achievement. Having a person actually feel or care strongly about a character is not easy to do.
