The Musictionary is a hand-held device that aids agents in identifying songs when they pop up inappropriately in a Suefic or songfic. It may be particularly helpful for agents who don't come from modern Earth, but considering most Sues' horrible taste in music, even the modern agent might benefit from keeping a Musictionary handy if they've been lucky enough to avoid the likes of Britney Spears, Justin Bieber, and One Direction. It was most likely invented by Spoofmaster.
