Favorite Vocaloid song?

Miku's "Love is War" is really the first time I ever paid any attention to the Vocaloids--until that song, I just blew them off as vaguely annoying mechanical noise. But that song had emotion--real emotion--and I was hooked.

But my very favorite has to be Haku's "Daughter of White." What "Love is War" started, "Daughter of White" finished, and I became a full-fledged fan. (For anyone familiar with Wicca--Wandering Witch, remember?--I was so impressed that Haku found her way into my personal pantheon of Goddess incarnations...)
