This comes up a lot, particularly in the metal scene, where it’s standard for bands to put out a lot of ‘demo’ tapes or releases.
These match up with the ‘demo’ type, but not really ‘promotional’ status: They are publicly available, usually for purchase (or back in the day, tape trade), and considered to be a part of the bands discography (shouldn’t be hidden from the artist page).
The description in the docs is pretty good: Release - MusicBrainz
Particularly this part seems to exclude metal demos etc:
“A give-away release or a release intended to promote an upcoming official release”
But it’s come up often enough that I wonder if we could add a line like:
A give-away release or a release intended to promote an upcoming official release (e.g. pre-release versions, releases included with a magazine, versions supplied to radio DJs for air-play). Usually not appropriate for publicly available stand-alone ‘demo’ releases.
Just checking if everyone’s on the same page re. how to use ‘promo’, and if anyone has any input finessing the text there. @reosarevok!
