Hatsune Miku: Project DIVA Future Tone (UP)

This only tracks while actually playing songs, not from idling in the menus. The easiest way to grind this if it's your last trophy is to put on any song, and turn 'No Fail' on. This way you can just leave it running, and just hit x to retry at the end of the song. As with other trophies, this will only pop upon the song ending after you've hit the number, so see them through!
