The >>'<< sign will indicate a pause in the description
1] Create in file manager >>Song'''.mp3<<
2] Display it in %_FILENAME% column [without extension, so that you will see >>Song'''<<, although appearing to you as >>Song<<]
3] Click that file in that column as if you are about to change its name. You should get a selection of >>Song'''<<
4] Now click on Windows Taskbar or any other file in the list in Mp3tag
In theory you did not change the name, because you backed out. In reality, if you check now the name of that file [in Windows Explorer], it will be >>Song<< and not >>Song'''<<. The pause are gone
