As part of its own Year in Review coverage, YouTube today posted a video of its own, inviting several "YouTube Stars" to participate in a giant mash-up music video, combining PSY's "Gangnam Style" with Carly Rae Jepsen's "Call Me Maybe."
It's entertaining if you like both of those songs - if not, it's about four minutes of pain. Even if you constantly watch YouTube to track viral videos, it's going to be tough to identify all of the "stars" in the video, but some you should notice include iJustine, Felicia Day, FreddieW and Rhett and Link.
The company also released its Top 10 videos of the year, which includes PSY's song and Jepsen's song.
