Basically all I was saying is you don't
have to create a
new library field... you can use an
existing field, and you can change how that field is "displayed" (i.e. named) in MC.
In my case, I use
Album Artist for sorting artists by last name, but how you are using that field makes sense. That said, there is already a built-in tag for
Composers, so I would have thought that imported classical music would auto-populate that tag for composer, but I guess not. Using
Album Artist for
Composer would never have occurred to me personally, as I have exactly zero classical music in my collection - I hate classical
almost as much as I hate rap
.
In any event, that is the beauty of MC, a myriad of ways to accomplish what you want/need in a way that works best for you. Regardless of how you handle it, you should check the box
Save in files tags for anything you manually populate to avoid ever having to do that again. I should also note however, you could have just restored ALL your Library meta-data directly via your MC24 auto-backup (which would have included your previously created
Album Artist Sort field), assuming you did not delete the MC24 backup folder.
