What i found after a long time of searching:
firefly smart playlists do (only?) respond to the mp3-tag %POPULARIMETER% .
This tag can be added by the software MP3TAG.exe (e.g.version 2.42)
And u must know:
– you type in one of those values: 1 or 64 or 128 or 196 or 255
– alternatively you can type in * or ** or *** or **** or ***** which will be translated in those above values by MP3TAG automatically.
– Firefly then recognizes that values as 20 or 40 or 60 or 80 or 100.
So in a smart playlist you can e.g use: rating >= 80 which returns the songs with ***** or **** respectively 255 or 196.
Unfortunately i haven’t yet found out to have that mp3-tag popularimeter show up in FOOBAR2000 !
