Some [url=v]guidelines for the use of Index Tracks have been added to the submission guidelines[/url]:
Index Tracks are used to denote groups of tracks (for example: movements in a musical piece, or where a range of tracks are given a collective title).
Index tracks should never be used ‘on their own’, they should always refer to a group of audio tracks directly below.
Index Tracks should only be used only when the release itself divides the tracks into named sections in some way. Index Tracks should not be used for denoting the sides, track positions, or separate media of a release (the track numbers are used for this), or for adding incidental information which belongs in the Release Notes.
