I have set tag "musicbrainz_albumartistid" =
"89ad4ac3-39f7-470e-963a-56509c546377"<br>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px;
margin-right:0px; -qt-block-indent:0; text-indent:0px;">I found
that tag in some Various Artists compilations I had brought in
from CD.<br><br>
Mythmusic still does not recognize the .mp3 with above tag as
compilation. </p>
<style type="text/css">
p, li { white-space: pre-wrap; }
</style>
</blockquote><br><div>I've had a closer look. The crucial tag is actually the TXXX (User Defined Text) field, which contains a list of name/value pairs. </div><div><br></div><div>Musicbrainz inserts a name/value of "MusicBrainz Album Artist Id"/"89ad4ac3-39f7-470e-963a-56509c546377", which is what Myth is looking for.<br></div><div><br></div><div>Gui tools seem to have trouble coping with this tag format. I suggest you use a command line tag editor such as exiftool (from libimage-exiftool-perl package) to see the raw tags (use the "-a" flag to see the whole TXXX list")</div><div><br></div><div>I use Quod Libet, which won't show the MusicBrainz TXXX tag after I've done a lookup. If I add tag TXXX=89ad4ac3-39f7-470e-963a-56509c546377 it results in a name/value of "QuodLibet::TXXX"/"89ad4ac3-39f7-470e-963a-56509c546377". As you're using a Musicbrainz product I wonder what you'd get if you try it ?</div><div><br></div><div>You should also try just setting the tag "compilation"=1. It may well set the TXXX field automatically.</div><div><br></div><div>Failing that you could use a command line editor to set the TXXX name/value pairs. Unfortunately I don't think exiftool can write ID3 tags but there seem to be plenty around.</div><div><br></div><div><br></div></body></html>
