In the past the artist refereed to their release as an EP, but now it seems they changed their mind and they call it an album. Should the release group reflect this or stay as an EP?
in this Release group “WAVESウェーブス” by ミカヅキBIGWAVE - MusicBrainz the bandcamp releases link to this url: https://mikazukibigwave.bandcamp.com/album/waves-ep, however that now redirects to https://mikazukibigwave.bandcamp.com/album/waves-album. and all references to the release in the description there mention it as an album too.
on their official store it is also mentioned as an album WAVESウェーブス – Mikazuki Bigwave
