Just Dance moves to the beat of two million sold worldwide

We've said it before and we'll say it again: we just don't get it. Somehow, Ubisoft's Just Dance has managed to become a full-fledged phenomenon -- we think two million worldwide sales means it's appropriate to call it that, right? Not only has Ubisoft received the honor that is boatloads of cash, but also the honor of having "the fastest-selling new intellectual property from a third-party publisher on Wii."

Perhaps the appropriate course of action isn't to try and dissect this, but to just close our eyes and go with it. Some of the songs aren't that bad, right? Or should we avoid sipping the Kool-Aid and quietly move to the side?
