初音ミクの消失 -DEAD END- (Hatsune Miku no Shoushitsu -DEAD END-)

Background
A crazed ultra-speed song with tempo reaching an upper limit of 240BPM about Miku's uninstallation. She realizes that she is not equal to a human being, still her wish is to keep on singing. Suprisingly, despite of being widely perceived as impossible for humans to sing, this song actually has a few fandubs and a NicoNico chorus of high quality. This type of songs are known as "dempa song" (meaning "obsessive song") in Japan. Most of the official Vocaloids also have their own "personalized" cover of this song as well.
