Yes! He's back to show us that he's a real...bird, and he won't dance to boyband music anymore! Total headbanging!!
Video Rating: 4 / 5

The movie shows three excerpts of videos analyzed in this experiment. Each excerpt is at a tempo different from the original song (Everybody, by the Backstreet Boys; 108.7 beats per minute [bpm]). The excerpts include synchronized bouts, periods during which Snowball bobs his head in synchrony with the musical beat for at least 12 consecutive bobs.
