changing the order of words with actions?

Hello friends, I come through this topic ask for your help because I did not find anything about it in my language (pt / br).
I would like to know how to create actions to change the word order, my case is the following:
I have some songs that are so TITLE:

ARTIST: Eminem
TITLE: When The Music Stops (feat. D12)
ARTIST: Eminem
TITLE: Say What You Say (feat. Dr. Dre)
ARTIST: Eminem
TITLE: 'Till I Collapse (feat. Nate Dogg)
ARTIST: Eminem
TITLE: My Dad's Gone Crazy (feat. Hailie Jade)

I wanted an action that moved the text TITLE from character "(" for ARTIST ...

ARTIST: Eminem feat. D12
TITLE: When The Music Stops
ARTIST: Eminem feat. Dr. Dre
TITLE: Say What You Say
ARTIST: Eminem feat. Nate Dogg
TITLE: 'Till I Collapse
ARTIST: Eminem feat. Hailie Jade
TITLE: My Dad's Gone Crazy

would it be possible???
I know of to do with the function FILENAME - FILENAME: %1 (%2) -> %1 - Eminem %2
but this way of hard work
I have little knowledge, having nothing on the Mp3tag in Portuguese and understand little English.
I thank the cooperation and patience of all, embrace.

ops: I'm sorry for English of Google translator :smiley:
