Vocaloid Radio is a fan-run web stream devoted to music sung by virtual singers — above all Hatsune Miku, the turquoise-haired voicebank who became a genuine pop star in Japan. Around the clock it plays tracks by Vocaloid producers, from early internet classics to the latest uploads, spanning electronic pop, rock and ballads. For the Vocaloid community, it is a 320kbps shrine to songs performed by software.
