A thought about the video: even in the dance version, Chrome Entertainment kind of blew it, by switching up locations too often and using closeups poorly and so not getting enough of the full dance formation, especially when the piston dance first appears. In fact, so far the rehearsal video is getting more views than either of the official MVs.*

*Though that may not last out the day, as the official dance MV is the version that seems to be going viral. ("Going viral" is relatively speaking; it's at 714,000 now, and my guess is that it surpasses a million views in the next day or so. Compare to "Gangnam Style," which is currently at 1.7 billion views.)
