Hi, I would like to rewrite the GENRE tag using a part of the old GENRE tag
Now genres are: a rock, a blues, a jazz
I would like to rwrite in: AA_rock, AA_blues, AA_jazz
Try an action of the type "Replace" for GENRE
Serach: a
(followed by a space)
Replace with: AA_
Watch out for files with the genre "A capella".
If you're not sure whether such a change would work for you, try Convert Tag -> Tag first.
You can see an immediate preview of your future Action here:
If it works for you, use it as @ohrenkino suggested above:
