I have a library that’s been growing for about 20 years now. I don’t think I got too serious until around 2009, which is when I discovered music servers to host my library and quickly realized how bad its structure was. It took years of me getting folders done correctly followed by then working on tags. Automation scared me to much since the results were not always 100%. Once it was done I have kept a system to keep it that way the best I can.

So for me once I get new content I use the app tagscanner to edit everything to the way I like, then I drop them into music Picard were I found a tutorial online a few years ago to set it up to just edit music genres. I found the one thing I never got right was music genres so finding this tool was incredible. Took months to run large sections of the library though. Now I got every track labeled with up to 5 genre tags. Once that is done I change folder names to what I want, drop them into my music directory folder which is root > artist > album (don’t care about year since it’s tagged). Scan music into my musicbee app and if any are missing covers I right click and tell it to find them. Then do a scan with navidrome to add it all there.
