LUCENTWAVES and Expression don't have front covers, so both tracklist and credits are displayed on the tray insert.

The reason why I scanned and used the back image instead of the CD is because I dislike scanning CDs. The website uses the back image as their front cover for those two, though the image used for LUCENTWAVES doesn't have anything printed on it while the physical release does (what I scanned).

The CD image is from suruga-ya.
