Yes, here a while back, I started to go through some of my albums (small chunck by small chunk) and started to convert the information in the Composer field from the generally standard "T. Shakur/J. Jackson" and such, into full names & Stage Names to end up like "Tupac Amaru Shakur (2Pac)/Johnny Jackson (Johnny J)"
Now, I'm fairly new to MP3Tag, so go easy on me here, but earlier I loaded up my main folder which contains all my Artist & Album subfolders and wanted to quickly find the albums I have already edited into that format, so I figured an easy filter on the Composer field of " (" would do the trick, as they are the only ones with ()'s in that field. But when doing so, it returns no results. Does the filter just not work with ( & ) or, what? Any help is appreciated.
