Metadata edited for the discs, so you can put them all into a single folder for programs like MusicBee and there won't be any issues. Cover has been embedded into every track. Artist section for certain tracks has been edited. Fukusawa is credited as an artist on every song, even on the songs with credits from other artists. His name from the dual credits has been removed, as it messes with the metadata (and he's already credited as the album artist for every disc).
