See https://musicbrainz.org/edit/72364147. A lot of artists release their own music digitally without a label, and in turn the digital outlets list the artist's name in place of a label (or a placeholder such as "123456 Records DK"). This has led some editors to add single-purpose "labels" for these releases.
I propose we add a "credited as" field like we have on most advanced relationships, so that Special Purpose Labels can be used, but the original label credit (be it the artist's name or otherwise) can be retained.
