If you fulfill certain conditions in the upcoming RPG 7th Dragon 2020, Hatsune Miku will actually sing to the Background music of the game. Why is this such a big deal? Well, partially because it is Hatsune Miku and partially because the Soundtrack of the game has been written by Yuzo Koshiro, who did the soundtracks for Streets of Rage, Shinobi and Actraiser. There are still no information on whether or not this PSP title will make it to the West.
