From: http://musicbrainz.org/doc/Style/Classical/Track/Title

For groups of tracks that are marked as part of a full work (with e.g. a header), add the full work title (as listed on the release) to all tracks from the work, separated with a colon. Do this even if the full work title is only on the release title (for example, in a release that contains only a full performance of the Goldberg Variations, the first track title should still be something like "Goldberg Variations: Aria", not just "Aria").

Please create an exception to this if the release includes only a single work, and that work is the name of the release. For example, this looks completely asinine.
