YouTube 2013 Rewind

Here's your chance to see what the world was glued to YouTube for in 2013.  The folks at YouTube made it themselves so it's a blend of all the hot songs, and interesting videos seen on their channel.  Keep an eye out for parody's of "Wrecking Ball", "What Did The Fox Say", "Harlem Shuffle", Screaming Goats, and "Blurred Lines" just to name a few.  Question is...Is it a good year if you can wrap up all the "interesting" things that happen for a full year, in only 5 minutes?
