I have many Title-Tags like for example "King (CD - WOW Hits 2006)" I want to remove the CD-Description or even better move it to comment or album-field.
I think it must be possible to use "Replace with regular Expression" to remove the CD xxxx including the sourounding Brackets. (Sometimes the title is also without closing brackets).
How can I do this?

You can use an action Guess values
Action #1:
_Action type:_ **Guess values**
_Source format:_ **%title%**
_Guessing pattern:_ **%title% (%comment%)**
