~~I would like to ask for approval of this edit: https://musicbrainz.org/edit/79279978~~ — nope, screwed up, cancelled.
Actually use this one: Edit #79281769 - MusicBrainz and it also contains corrections to the track titles (double-checked with discography entry and print booklet).
The release was originally missing a track, and I have just added it. Without this being approved, I would be unable to add the disc ID from the CD that had just arrived in mail.
P.S. I have also changed the release artist, per this discussion: How should we handle doujin music? - #33 by tojikomori
