愛とソンジMikuTap Qplayer app for iPhone and iPad
Very interesting music patapon, rhythm and DJ feel.
That may play different from the Hatsune Miku hand-game, this thing is more like a combination of puzzle and beat DJ.
mikutap is a music software, you can freely click on the screen so that miku sing a different song, each area corresponds to a princess His Royal Highness, very brainwashing.
