Excellent! That worked perfectly. Now I have tried using an older post to help with the next part of moving the featured artist over (you were directly involved in getting me to this format string in fact), and while I do not understand it, it seems to get me somewhat close to a desired result.

And using an adapted version from my slight understanding, I attempted to change it to fit my goal here. I just did this:  
Field: artist  
String: %artist%\\$mid(%title%,$add($strstr(%title%,'Feat.'),6),$len(%title%))

From this:  
\*\*ARTIST:\*\*Cash Cash\\Dashboard Confessional  
\*\*TITLE:\*\*Belong (feat. Conor Maynard) [BEAUZ Remix]  
\<\<\< To This \>\>\>  
\*\*ARTIST:\*\*Cash Cash\\g (feat. Conor Maynard) [BEAUZ Remix]  
\*\*TITLE:\*\*Belong (feat. Conor Maynard) [BEAUZ Remix]  
I'm positive that I'm just not understanding this, but do you believe this it workable?

I also tried using a guess value using  
Source Format: %title%  
Guessing Pattern: %title% (feat. %artist%)  
**Which yielded no change**  
and  
Source Format: %title%  
Guessing Pattern: %title% (feat. %artist%  
**Which yielded this:**  
\*\*ARTIST:\*\*Conor Maynard) [BEAUZ Remix]  
\*\*TITLE:\*\*Belong  
Which doesn't really seem any closer to my goal.
