I was amazed in my case how much time I've spent on standardising artist names said:
I really only want to be able to browse my Library, or search for what I want to listen to. Most non-classical music finds its way into an appropriate folder (I want the album in a file titled "ABBA" or "Agnes Obel" in alphabetical order by first name if they use such. Then I can go to my Non-Classical section and find a list of around 100 Artists, each sub-folder having my entire collection of ABBA or Agnes Obel.
With Classical, the metadata picked up while ripping is dire, but editing this metadata is time consuming and, in my opinion, unnecessary.
Once ripped the album may find its way to say my Beethoven folder, but just as likely into a Ludwig van B folder, or Karajan, LSO, Brendel or whatever the metadata thinks most important. I want it all in my Beethoven folder, so I use Windows' simple Cut & Paste to move any misfiled folder to my Beethoven one. Simple 2 minute job.
If I want to see my Brendel music I just use Search and it will find amongst other works his Beethoven sonatas.
In my Classical main folder, I have about 100 Composers, plus 3 or 4 multi-composer (Collections) albums that I move to Instrumental, Orchestral, Choral and Opera, etc. Again dead simple using Cut & Paste.
Albums with say 2 piano concertos are easy to re-file from where the metadata plonks them - probably under the soloist - by moving the 3 or so tracks of Composer A plus the artwork to his folder and Composer B’s tracks plus the same artwork to his folder. More than 2 composer albums go to Orchestral or other collections folder.
So I use an identical system that Tower Records (if you're old enough to remember browsing their racks to CDs) used to offer - Main sections of Classical, Non-Classical (I don't need a Jazz section), World & Weird, and one or two others - then by artist (composer for classical) and perhaps further sub-folders if you need to separate symphonies from concertos or whatever.
The old (are they still going?) Gramophone and Penguin Guide Books also used this filing regime. I'm less likely to be looking for a particular Genre, but I occasionally use my control app (BluOS) to list albums of a particular genre.
I recommend this simple and familiar-to-everyone system as it's so much easier than messing with metadata.
