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?
