For the files themselves lately I’ve been doing something like Country of Origin/Artist/Original Year - Album (Catalogue Number) (Release Year)/ (used to do it without the country, but at one point they became way too many, and I don’t really like organising by letter or whatever). I love foobar2000 with Facets because of the fact that you can shove any arbitrary tag into the files and then have columns show it (I’m doing that with the countries for example), but I’m now suffering a bit because of that habit - I started also self hosting my library and Navidrome that I’m using doesn’t like just any tags that you throw at it (it especially doesn’t like it if you have multiple releases of the same album that have come out in the same year).
