I tag everything the same way, no matter what I use to listen to the music, the OS I use, tag app, music source etc.  Just Artist, Album, and track number.  Clear all the other fields.  For classical, I appreciate that there can be different labels releasing different masterings of the same recording, or different conductors of the same piece, or a given conductor conducting the same piece with different orchestras etc but for me I&#x27;m happy sticking that info as part of the Album. For example: Gurrelieder (Boulez).  I don&#x27;t see any point in getting anal about it all. You can stick the notes in the folder you store the music in, or have filenames with extra details but as long as the music player lets you drill down from artist to album, and plays the tracks in the album in the correct order, that&#x27;s good enough.  I don&#x27;t waste my time with cover art etc because if I want to look at it I can do that on a pc or in real life; i&#x27;m never going to be staring my my phone while it&#x27;s playing, and it&#x27;s never going to be quicker to wade visually through cover art to find what you&#x27;re looking for (although I guess it might aid lazily browsing through your collection if you&#x27;re not sure what to play).
