I am a tech savy person, but I have absolutely 0 experience working in Linux or doing any sort of networking so I'm getting lost.

You have no experience with Linux so you need to learn something. It might as well be Docker.

Have you looked at Linuxserver.io ? They've got Docker Compose configurations for a bunch of media applications, among others.

Linuxserver also have descriptions and Docker configs on Dockerhub.

So maybe that can help you start.

I use KODI as a music video player.

I manually fill XML .nfo files with the information for each music video. Then I have KODI rescan the music video directory and the new ones are added to the library.

It might sound like a lot of manual work but it only takes a few seconds per song. Considering you say you listen to the same songs a lot, it might not be a problem for you.
