Move "Featuring" from Artist to Title

[djdizzle]

@DetlevD

Action: Guess values
Source format:

%ARTIST%$regexp(%TITLE%,'^(.+?)\s+[[({<]?\s*(?:featuring|feat\.?|ft\.?)\s*([^])}>]+)\>\s*[])}>]?(.*)$',' feat. $2$3+++$1',1)

Guessing pattern:

%ARTIST%+++%TITLE%

I have tried the above expression (screenshots attached), but the results were not as intended.

I have racked my brain trying to figure out why the title is disappearing altogether, everything else appears to be working properly. Any suggestions?
