Music player controlled remotely. Can this be done?

I don’t have one, but I’m curious. Plexamp is a client, right? So I’d still need a Plex server. What does that Raspberry Pi setup gain over just having Plex client (or Plexamp) and server on the same Windows desktop computer?

Space by the stereo receiver in the basement is not a problem. It’s behind a closet door and having a desktop tower by it would be fine. I just don’t want to put it upstairs since there isn’t a good spot for it.

I didn’t realize that you can control Plexamp from another Plex client. That kind of sounds like the Plex Companion thing I mentioned above which I thought had disappeared. That would be great. Is there anywhere to read up on how to do this remote control?

Say I have Plexamp installed on that Windows desktop. If I install Plex mobile app on an android tablet, can I remote control the desktop’s Plexamp client?

Interesting. I found on this page - Plexamp - Frequently Asked Questions - the very last line says…

Can I remote control another Plex app?
The Player selector in the app menu lets you choose which player to use for output. You can choose Local to play on Plexamp itself or choose another Plex app to control.

I also see this page https://support.plex.tv/articles/201358253-choose-a-player/
which is all about choosing a Plex player app from a Plex controller app so I guess you can control any Plex client with another one. That right?

I guess I need to get the mobile app and do some experimentation.
