this update is beta yet, multitags value don't work as they should.
so only download if you are interested in development.
i added %album artist% and removed the tracklist form %unsyncedlyrics%, no problem with that.
i also want to change discogs style and discogs genre into a multivalue tag for foobar2000. this doesn't work yet. the problem is described here:
/t/9432/1
edit 2010-01-21:
there is a new Beta2 Version. the old didn't work due to changes at discogs.com.
edit 2010-01-24:
the changes of this Beta Version are now included in the full package in the starting post.
