My view is that not having separate artist folders is wild, but hey, whatever works for you.
All in all however specific folder structure is not terribly important to me; what’s important is that the tags are in order and that I can make the app I’m using present the stuff in the manner that I want.
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).
Now I’m sad that it already has a name - I don’t get to name my diagnosis.

The problem is when they’re perfectly organised in a different manner from what you expect :D
I do, but shush, don’t tell anyone! Still, nobody has complained about that so far.
