is there any way to mass-copy tags from file to file with Tag? For example, I have an album in MPC format, and a FLAC copy for archival (with exactly the same file names). I'd like to copy all tags from the MPCs to the FLAC files (not the APE tag itself of course, I mean APE -> VorbisComment), because re-writing all those "Composer" and "Producer" tags (which, unfortunately, happen to be different from track to track in some cases) would be a pain for several albums.
I tried using --fromfile with wildcards, but that didn't work out.
Thanks in advance
