Ah, so you're enjoying some Touhou music? If you're going to be using a Sakuya avatar, you're going to have to listen to The Maid and The Pocketwatch of Blood along with Lunar Dial. Flowering Night is good, but it does not compare to her original two themes.
and Necrofantasia, Star Casket, Love Colored Master Spark, Dream Battle, Invisible Full Moon, Voyage 1969, Immortal Smoke~Reach for the Moon, Septette for the Dead Princess, and MANY MANY MORE. You know what, Touhou just has amazing music.
