For example, tons and tons of soundtracks in Musicbrainz are wrongly credited. (As in, neither the composer NOR the performers were credited - the information was just wrongly assumed to be the same from a sequel/prequel or made up.)
Editing the tracklist on the release is a given - it's a one-step edit. However, all 15 or however many of the recordings also need their artists changed.
Makes sense to add a checkbox or something to allow an editor to say "copy these new artist credits from the tracklist to the recordings too".
