Some directories seem to "know" they contain media files, others don't. I am not using iTunes/Music (app) btw.
For some directories, in Finder, List-view, when I click on the headings, I can add extra columns such as Album and Genre - let's call those "media columns".
However when I created a new (test) directory and placed some mp3 files inside it, then right-clicked that directory's headings, no options to add media columns were given. These mp3 files did contain ID3v2 metadata btw (I don't know if that's relevant).
What is it that distinguishes / determines these two types of "add column" behaviour?
