Well, it's only a problem if vorbis tags also exist since, AFAIK, no
other tag parser merges values for duplicate keys. Checking in ogg
files can be done as well (though I expect the reference decoder chokes
on them). None of the tag editors I have even allow editing ID3 tags on
ogg files, so I can't test it. I have a patch for when one appears
though (not going to submit since there's no need at the moment). If
anyone can come up with one using some silly tag editor, I'll submit it
as well.
