i have a "system" which is constantly in flux, but here goes (i refuse to change the [album] name)
i use [date], [date (release)], [country], and a few customs [album source], [album information]
in RMC i have a preset that does some stuff to name folders on disc, (forgive me, i have 11 versions of Nirvana Nevermind)
Nevermind-1991-FLAC-CD-USA
Nevermind-1991-FLAC-Vinyl
Nevermind-1991-FLAC-CD-JAPAN
Nevermind-RM 1996-1991-FLAC-CD
Nevermind-RM 2011-FLAC-HD
so [album], if date release is empty or equal to date, then date, else RM-date release-date, file type, album source (then country if i need it to differentiate further)
[album source] is a manual check field for CD, HD (i.e. anything over 16/44), Vinyl, Bandcamp, Itunes...etc. pretty obvious
i also have an [album quality] field which is calculated from variables (lossy bitrate) but i'm phasing it out as i weed my lossy
then i put the album info into [album information], i try for a template, i.e.
remastered 1996 - MoFi gold disc
remastered 2011 - HDTracks
remastered 2011 - DGC 20th anniversary boxset
original 1991 - Japanese release
and finally all of my boxsets (and some "created" boxsets like the new 2014 Led Zep remasters) get a series tag so i can view them as actual boxsets as well
so i can sort on date (release), album information, album source, country...etc. the views are pretty flexible
i'm currently working on catalog #'s but i've only started ripping with them very recently so i have a long haul in front of me
i won't claim to have the best system but it's working good for me and i can view things very quickly and easily and pick what i want, it looks great on disc with a folder structure and the [album] name stays what it should be
thank goodness for MC, if it can satisfy my OCD and penchant for completist collecting it can work for anyone. hope this give you some ideas at least...
