It’s a bit of a process to get it going, but it’s worth it for me so that I can use my phone to cast directly without needing to use a smart home device.

I use plexamp as well, I think I bought Plex Pass specifically to have it.
You can install a headless plexamp client onto a Raspberry Pi and have it hooked up to an audio receiver for seamless music casting.
A space is a collection of rooms. So you have a clean list of spaces, then when you click into one of them it shows all the rooms that it contains. Without spaces, every single room is shown in one big list.
Element x still doesn’t have support for spaces. Trying to navigate between rooms just by scrolling through one huge list is a nightmare.
Lidarr also serves as a music organization tool. You can set up rules for folders and how music files should be renamed. It can also apply metadata tags automatically.
