Some releases have no defined track order. For these releases, leave the track number blank.
Some tracks are hidden or unnumbered. For these tracks, leave the track number blank.
Medium sides should be indicated with a letter (A, B, C, etc.) before the track number.
For most releases this will be similar to A1, A2, A3, B1, B2, B3.
If the numbering does not restart at 1, use the number on the release: A1, A2, A3, B4, B5, B6.
For releases which already have their own lettering, follow the release: R01, R02, R03, S04, S05, S06.
Some releases have no side indication. In this case, if there is a matrix number or other identifier which distinguishes them, treat the lower-sequenced one as side A.
- R de Rumba has its own lettering, and zero-pads the numbers.
- This single has different catalog numbers on each side. The lower-numbered side is considered “Side A”
Some single-sided media have “Sub-tracks”. This applies to CD “indexes”, DVD “titles”/“chapters”, and 4 or 8-track cartridge “programs”, and is also common in production music to identify alternate versions of a track (e.g. a 30-second excerpt).
For these releases, separate the main track from the sub-track with a period: 1.1, 1.2, 2.1, 2.2.
If there is only one title on a DVD, just use basic track numbers 1, 2, 3, 4, etc.
If a DVD includes a tracklist which doesn’t include some chapters, follow the tracklist numbering. Leave any skipped chapters un-numbered.
Alternate audio tracks
Some formats (DVD, SACD) provide alternate audio tracks within the same title. For these, separate the audio track identifier from the track number by a number sign:
- “1#1, 2#1, 3#1” for the first three chapters of the main track
- “1#2, 2#2, 3#2” for the first three chapters of an alternate track
- “1#3, 2#3, 3#3” for the first three chapters of a second alternate track
Note that this could be combined with sub-tracks (above): 1.1#1, 1.2#2, etc.
- automatic-sequence double (or triple) albums
- Some vinyl releases are designed for use on an automatic record changer. In these releases, all of the “top” sides are played, followed by all of the “bottom” sides. Letters should be assigned to the sides in play order, which may result in a strange displayed track order:
- side in cat. no.
- Some releases include the side as part of the catalog number on each side (e.g. 8326-A and 8326-B). In this case, just use the side indicator (e.g. "A" or "B")
- double A-side
- Some releases have other unusual numbering. (e.g. double A-sides, side AA, side AAA) For these cases, use whatever is printed on the release.
- parallel grooves
- Some vinyl records have several sets of parallel grooves. Treat them the same as alternate audio tracks, above. Ordering is left to the discretion of the editor and voters.
