YouTube Rewind: Turn Down for 2014 – the epic end-of-year tribute to all things internet. This is an unprecedented mashup, featuring over 120 YouTube creators and taking place on four continents. This Rewind represents the culmination of more than 6 months worth of inspiration, thousands of hours of work and collaborations with hundred’s of YouTubers.

The video has plenty of cameos including the top-viewed trending videos, music videos and commercials of the year. The Ice bucket challenge is very prominent, as it was throughout the whole year, as was 10 Hours of Walking in NYC as a Woman, a video produced by anti-street-harassment group Hollaback. Mutant Giant Spider Dog topped off the list of viral videos (113 million views) and Katy Perry’s Dark Horse gained more than 716 million views.

The 6-minute video is jam-packed with YouTubers like Jenna Marbles, Tyler Oakley and Michelle Phan and the late night TV hosts also appear Jimmy Kimmel, Stephen Colbert, Conan O’Brien and John Oliver.

The soundtrack to this jazzy mashup is a medley of the biggest tracks of 2014, everything from Frozen‘s Let It Go to Iggy Azalea and Charli XCX‘s Fancy to Meghan Trainor‘s All About That Bass to Pharrell‘s Happy.

This video is light years away from the very first Rewind in 2010 which was basically just a mashup of the years most popular music videos.
