The idea is contained in this epilogue-ish explanation
In other words:
I finally can sort my FILENAMEs / TITLEs exactly how I need to. And so I wish I could also have that sorting applied to them every time when I sort by ALBUM. Right now I have to do this manually, i.e. in two steps: first sort by [Column for] FILENAMEs or TITLEs and then sort by [Column for] ALBUM [because Mp3tag retains sorting in the FILENAME / TITLE when I clicks headers of other Columns]
The $replace(%ALBUM%,'<',,'>',) code for ALBUM provides me with such desired order
Blade Runner <Movie Score>
Blade Runner <Movie Score> <25th Anniversary Edition>
Blade Runner <Movie Score Unreleased> ! ! ! ! ! ! ! ! ! !
Blade Runner 2049 <Movie Score> <2018 Eisengeist Edition>
Blade Runner Orchestral Adaptation
instead of the default one which looks like this
Blade Runner <Movie Score Unreleased> ! ! ! ! ! ! ! ! ! !
Blade Runner <Movie Score>
Blade Runner <Movie Score> <25th Anniversary Edition>
Blade Runner <Movie Score> <Esper Retirement Edition>
Blade Runner 2049 <Movie Score> <2018 Eisengeist Edition>
Blade Runner Orchestral Adaptation
[I had to add that `` ! ! ! ! ! ! ! ! ! !`` as a maerker to the ``Blade Runner <Movie Score Unreleased>``, because I could not make it stand out in any other way because the Forum kept messing up what I was writing]
As for the FILENAME / TITLE it has been thoroughly discussed in this topic. But it comes down to the same principal rule: of putting certain "annotations" and markings before others; with the ones contained in [ ] being the foremost while the ones starting with # being of the least "importance" to my naming system]
