I added several "user library fields". One for the name of all the lists wich I called "Best Of." Then one field per list wich contains the ranking. "RankPF", "RankMC", "RankRS" etc.
Tools > Options > Library & Folders > User Library Fields > Add Field ...
"Best of": Change name accordingly, remove flags except "Audio" and change "Data Type" to "List".
"RankXX": Change flags and set "Data Type" to Integer since this field will store numbers.
Repeat the last one for each "best of" list you want to add.
I then added viewschemes:
Right click "Audio" > Add View Scheme
Under step 1:
Add one or two fields here, click "Add" for each.
Year - Type:Library field, Field:Album < Only for lists where year is of concern.
Album - Type:Expression, Name:Album, Expression:[RankXX]. [Album] < Adds the ranking before the album name.
Under step 2:
Change to the name of the list e.g. "Pitchfork Top 50"
Under step 4:
Click "Edit Included Files"
Rules:
"Best of" - is not any - <empty>
"Best of" - is any - "list name" < You'll have to tag some albums first for the list name to show up.
Modify results:
Remove all and add:
Sort by - Rank(a-z)
When viewing your new scheme: Click "Pane" And change "details" to "album thumbnails". Click pane again and choose "Customize Current View" and replace the code under "Thumbnail Text" to this: "[RankPF]. [Name]
[Artist]" (without the brackets)
Harder to explain than to setup really.
