Microsoft has created a program called Songsmith, where the idea is you sing to it and it spits back musical accompaniment. So people have been giving the musical equivalent of the Turing Test: if you isolate the vocal track from a popular song and feed it to Somgsmith, will it return a reasonable (or at least hilarious) musical background? Here are some such attempts: Ozzy Osbourne's Crazy Train, Billy Idol's White Wedding, Rush's Tom Sawyer. But someone took it one step further: a Barak Obama speech.
