Comment 6 for bug 5465

Further, it seems that this particular file had multiple ID3v2 tags written to it. Using a tool to remove the tags will delete the last tag written bring the old tag up to be edited or removed. I suggest removing, then adding a fresh tag with your choice of information.

The tool that I used to do this is 'kid3'. This has solved my problem which is not in fact a problem of persisting ID3 <> ID3v2, but MP3's holding more than one of each version of the tag.
