Does it actually check the CRC, or is there some way for me to do so? I
see the output from hogg dumpraw, but am not sure how to interpret it.
In other news, the MediaMonkey developers believe this is a bug in a
(possibly) older version of vorbis_comment_add_tag():
Does this seem right and/or shed any light on how to undo the damage?
