Anyone who is checking out Haruka: go for the tracks she composed herself. They're usually haunting hybrid of fantasy and magical folk. Think Legend of Zelda at its best. Even though they're her most popular, Her "best-of" albums are good, but you have to weave through mediocre anison tracks to find the gems, since they're mostly theme songs Haruka has been handed to sing. It's everything else that should be checked out first: her work with doujin circles of Maple Leaf, tieLeaf and units like Canoue and kukui, her mini-albums and her studio albums. A lot of enchanting music to be found there, most of it by Haruka herself!
