I tried to find the answer to my question, but was unable to. Maybe someone readily knows the answer!
I am starting to use the 'Band' (Album Artist) field, specifically for Mixed Albums, whereby the DJ is the Album Artist and per track Artists may differ. Now, for these instances, I want to convert the Tags to filenames like so:
%album% (%band%) - $num(%track%,2) - %artist% - %title%
Since I have many albums already tagged where %artist% equals %band%, I only want to include %band% in the filename when the tag field is not empty.
So, the question is: in the string above for converting tags to filename, is there a possibility to only include the value of the band tag (including the brackets) when this field is not empty?
Guys, after having looked around a bit further I managed to answer my own question:
%album%[ (%band%)] - $num(%track%,2) - %artist% - %title%
