I’m using mp3Tag since many years and I can’t appreciate enough the work and engagement of the coders and providers.
Ok, lets come back to the topic.
Bug: When I takeover the file name from tag with following format string
%artist% - %title% [%year%]
the year in the file name is taken over but not in square brackets. It works with all other brackets { } ( ), but not with [ ]. Conversely, if I have written the year in [ ] in the file name already and take it over to the tag with the same format string, the year is copied to the tag correctly without any problems.
