the "part of" ARs on the related works are displayed as "parts:" which is confusing.
The same happens with versions and medleys too.
It seems that it always uses the same order, regardless of the actual direction of the relationship, e.g. http://beta.musicbrainz.org/release/e32ad2bd-82e9-473f-9b44-0539bc2920ca/edit-relationships says "medley of" which is correct, http://beta.musicbrainz.org/release/c4944da6-84d6-498a-9aaa-94687305c8c2/edit-relationships also says "medley of" which is not.
