New user here. I read the FAQ and searched the forum but couldn't find an answer.
My music library is mainly m4a files from ripping CD in iTunes (ver 126.96.36.199).
I then use MusicBrainz Picard (with last.fm plus plugin) to fetch values for, among others, "genre" tag.
This typically yield multiple values in the tag, e.g. "Folk; Rock; Bluegrass"
When I hit save in Picard, I then look in Mp3tag and see "Bluegrass" as value.
And when I look in iTunes, I see "Folk" as value.
From my tests, it seems that Mp3tag always displays the last values, and iTunes the first.
Value "Folk" is also displayed in Windows Explorer and in TagScanner.
Is this a normal behavior, working as designed?
