I actually feel like there's still lots of variety in their albums, especially their last 2. Uroboros had songs like Vinushka, Red Soil, Glass Skin, Stuck Man, Reiketsu Nariseba, Ware, Yami Tote..., and Dozing Green. DSS had The Blossoming Beelzebub, Amon, Lotus, Diabolos, Vanitas, and Ruten no To which I think are songs that are all different from each other. I do think Macabre and Kisou are some of the album with least variety.
