I'm in a playlist named Before the 90's, Viewing by Track, and I can't get Sort By > Define Custom Sorting to prioritize Original Year, over Year. It always prefers Year first. I've tried Define Custom Sort By
1. Original Year/Year/Artist
2. Original Year/Year (yyyy)/ Artist
3. Artist/Original Year/Year
When I switch between option 1 and 3 it's visible that there is a priority order.
The reason I'm trying to use two different "years" is because I have some movie soundtracks and compilation albums that contain songs from different years than the album release date, and I want the songs broken up from the album, within the playlist. So I set the Original Year in Tags (2). For example Goodfellas is a movie from the 90's, but each song is set between 1950-1970.
I thought it would be more streamlined to use Original Year only on an as-needed basis. Otherwise, you'd have to tag Original Year for your entire library, and any new tracks added, just to bend around a few albums.
