The call came down from on high: “Now watch me whip. Now watch me nae nae.” And the world heeded that call over 115 million times. But fast away the old year passes, and so Mic’s Liz Rowley has assembled a list of the 10 most-watched YouTube videos of 2015. Topping the survey, unsurprisingly, is “Watch Me (Whip/Nae Nae)” by Atlanta rapper Silentó, proving definitively that music videos and dance crazes alike are both still alive and well in the new millennium. Music actually dominates Rowley’s countdown, from a Will Ferrell/Kevin Hart lip sync throwdown on The Tonight Show With Jimmy Fallon (over 54 million views) to a Britain’s Got Talent audition by Calum Scott (over 38 million views). In retrospect, recycled content from late night TV was big in 2015, too. Besides the Fallon clip, the list also includes a presidential “Mean Tweets” segment from Jimmy Kimmel Live! (over 34 million views) and James Corden singing karaoke with Justin Bieber on The Late Late Show (over 43 million views). Stephen Colbert had better get cracking if he wants to catch up.
