For Hatsune Miku's 10th birthday, Kenshi Yonezu wrote the turquoise-haired anime darling an apocalyptic song. "Suna no Wakusei" (English title: "Dune") finds Yonezu, under the alias Hachi, programming the avatar for singing-synthesizer software Vocaloid to sing about a "desert planet" where life has eroded and "no grass will grow for the next millennium." It's seemingly more climate-change-centric than celebratory, all set over an unsettling mix of guitar and mocking cheers.
