Move a featured artist from the ARTIST to TITLE tags

[ohrenkino]

I would apply a filter with
%artist% HAS feat.

and then use a single action of the type "Guess value" as described in this thread:

Move "Featuring" from Artist to Title

Action: Guess Values Source Format: %title% $regexp(%artist%,(.*) Feat. (.*),'('Feat. $2')' +++ $1) Guessing Pattern: %title% +++ %artist%
