There are “releases” being added to MB as bootlegs that are really just playlists. However, they have fan made cover art. The editor says that “I have SoundCloud playlists + I’m preparing download link for these albums (on Google drive)”. Is this enough to be considered a bootleg on MB?
I think your inclinations are correct. Twenty-five years ago, I’d have never considered the mixtapes I made for friends to be “releases”, and that analogy still stands (to me, at least) despite how technology has changed since then.
I hope the user who added this release, though, will consider adding any unreleased material as standalone recordings if they’re not already in MusicBrainz.
That’s what I suggested to them. To add any leaked recordings that aren’t already on MB as standalone recordings. They seem to understand about the compilations now. There are a bunch of these under Lana Del Rey and it seems that a group of editors have been doing this for a while and just weren’t noticed. I’ve put in edits to remove them. Hopefully the recordings will stay in the database.
