User:Hawke/Proposal/Vinyl track numbering
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.
Some releases have more than two “sides”: This is common on older multi-disc vinyl records designed for a stacking turntable. For these, use A, B, C, D, etc. as applicable. This means that track ordering may be strange, e.g. A1, A2, A3, D1, D2, D3, B1, B2, B3, C1, C2, C3. (second side of first disc is the end of the release).
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 (in that case "A" or "B")
Some releases have no side indication. In this case, if there is a matrix number or other identifier which distinguishes them, treat the lower-numbered one as side A.
Some singles have other unusual numbering. (e.g. double-A sides, side AA, side AAA, side A/side 1, etc.) For these cases, use whatever is printed on the release.
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.
