I'm talking about the default Audio > Artists view. See screenshot. Sorting of the albums at the top is now correct, new to old, sorted as described previously, because Year - Album wasn't working.
By "wasn't working" I guess you mean "not producing the effect I wanted" because [Year - Album] works fine; it's a built-in field and does what it's supposed to do. Using it in a sort requires understanding it.
All that field is, is a calculated field that prepends the [Year] to the [Album]. Which means if you sort or group by it, newest albums will come first (or last) because [Year] is at the start of the string. This works fine when you view Taylor Swift. It doesn't work so well when you're viewing "All Artists" because it will list all the albums by year first, regardless of the artist.
Now when you use "Grouping" down in that lower pane, the File List, it will only group by a field. You don't have the same flexibility in defining custom sorts. By default it groups by "Album" and that is a special case, hard-coded into MC, that doesn't actually sort/group by album, it sorts/groups by Artist then Album, but displays only the album name and adds the words "by [Artist]" at the end. Other fields don't get that special treatment.
So you can group by [Year - Album] and if you do, all your 2019 albums will come first, regardless of who made them, when you're viewing all artists. It will look like you want when you view Taylor Swift though.
If you want it to sort correctly all the time, you could group by a calculated field you create, called "Album Artist - Year - Album" which you set to type calculated data with this definition:
[Album Artist] - [Year] - [Album]
That will always sort correctly. You can decide if you like how it looks.
Hope this helps...
