When the Analyze Volume or Level Volume commands are used,
MediaMonkey stores volume leveling information to the tags and the db.
As of MediaMonkey 3.0.2, it is possible to delete this information by
editing the Track Volume co-efficient in the Tracklist, however, it is not
yet possible to edit the Album Volume co-efficient, or to mass-edit
Volume Leveling coefficients.
This functionality is planned for a future release.
