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, and “programs” on 8-track cartridges. 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).
DVD releases may have several titles. The track number should be displayed as the DVD title and chapter numbers, separated by “-” (1-1, 1-2, 1-3, etc.)
Some releases (e.g. production music) use “sub-tracks” for alternate versions of a track (e.g. a 30-second excerpt). Use a period to separate the main track number from the sub-track. Zero-pad the sub-track to two digits. This may also be used for CD index numbering.
