The 1st column of the table "Appears on releases" of the Recording page (#) shows two numbers: TN/NT (TN = track number in a medium; NT = number of tracks in a medium). But as the medium number in a release (MN) does not shown, the exact track location still not defined. This is very inconvenient for the releases with multiple mediums (5-10-20...), the recording is hard to find in a release, e.g.:
http://musicbrainz.org/recording/062a4140-56f6-4305-98c6-30939455b145
It would be very useful to display this line as MN/TN/NT.
(Or maybe MN/TN only, if a third number is too hard to add. The information about MN is more important than about NT.)
