I am selecting bunch of tracks in various albums and artists by highlighting them in macOS iTunes/ Music App to upload into mp3tag to work on them. Earlier iTunes/ Music App would allow opening such highlighted tracks into another program e.g. mp3tag. However, now that feature seems to have been stripped off.
Now I have to work one by one: right click on each track, select "Show in Finder" and from the finder window load into mp3tag. It's so painful 
Does anyone know a better way to mass upload selected tracks from iTunes/ Music App to mp3tag?
