I am trying to format my classical music. So in the title field I want to move the Op. number to the beginning. So for example the track title might be: Piano Sonata No. 2 in B-flat minor Op. 35 "Funeral March" - 2. Scherzo I want it to be: Op. 35 - Piano Sonata No. 2 in B-flat minor "Funeral March" - 2. Scherzo Of course the Op. number isn't always going to be the same. I tried to create an action myself for this, but it's too difficult. Any help would be appreciated, Thanks! ---

If the "Op." is the separator and always followed by a number, you can try an action of the type "Replace with regular expression" for TITLE Search: (._) Op. (\d+) (._) Replace: Op. $2 $1 $3 ---

Thanks! I have noticed one flaw: if the Op. number is at the end of the title it will only take the first digit. So "Op. 23" is moved as "Op. 2" and "3" stays at the end. I added an action to the group that adds text to the title before running your action & then removes it after running, which solves it. ---

So "Op. 23" is moved as "Op. 2" and "3" stays at the end. ... That's another starting point, but you can build quickly the new regular expression, which works also without the last part " bbb".
