I am trying to do something extremely simple. Take the GENRE tag and put all of its contents insider of parenthesis.
%GENRE% -> (%GENRE%)
However, I cannot get this to work. If I use 'Convert Tag-Tag', the preview will display the results properly but if executed it will just replace the tag with an empty field. This is also true if I try to use the equivalent form of Regular Expression to do the same.
I noted that the , is used to escape ( in the MP3tag documentation. Indeed, I have been able to get the parenthesis to appear properly using:
Action -> Format Value: GENRE -> ,(%GENRE%)
but that leaves me with a comma out front. But I am unable to remove that comma without blanking the entire tag.
What am I misunderstanding here?
