Apart from a definition of “Hidden Track” MB Terminology offers a link to Style Guidelines’ Multiple titles / Splits. According to this multiple titles on one track should be credited “Title 1 / Title 2” (if both titles are known). So it seems reasonable how the last track on Björk’s Vulnicura Strings is credited - “Family / Black Lake (viola organista version)” and the recording is a compilation of two other recordings. On Discogs it’s 9a and 9b, so everything looks fine.
Except there was a discussion about “Hidden Tracks” on this forum with another conclusion. “Artist intent overrides Style Guidelines” and so the “Hidden Track” is not included in the title (hidden) and only named in the recording which is a recording of the two separate tracks. Of Monsters and Men’s Yellow Light + Hidden Track recording was an example. It’s a quite similar case.
Now, probably Family / Black Lake (viola organista version) should be renamed to “Family” (track title only) and relationships for the recording should be changed to recording of. It’s probably no compilation of if the title mentions only the first part (and information would be redundant anyway).
I don’t want to start a new discussion about hidden tracks as there were answers from this earlier discussion:
I’m only seeking some confirmation before I start editing.
