YouTube just celebrated its 10th anniversary on Feb. 14 and South Korean rapper Psy is apparently the king of the video-sharing site. Two of the 10 most viewed YouTube videos of all time are music videos of Psy’s songs.

However, Psy is not included in the list of musicians honored in the recent YouTube Music Awards 2015. Psy's fellow South Koreans, the 2NE1 girls, are among the honorees along with Rihanna, Sia and Psy's "Hangover" collaborator Snoop Dogg and many others.

Most of the videos in the list of 10 most-viewed YouTube videos of all time are music videos of collaboration songs, which include Justin Bieber’s “Baby” featuring Ludacris, LMFAO’s “Party Rock Anthem” featuring Lauren Bennett and GoonRock and Katy Perry’s “Dark Horse” featuring Juicy J at numbers two, three and four, respectively.

At numbers six, seven and eight are also collaboration songs, which are Eminem’s “Love The Way You Lie” featuring Rihanna, Jennifer Lopez’s “On The Floor” featuring Pitbull and Shakira’s “Waka Waka (This Time For Africa)” featuring Freshlyground.

At number five is “Charlie bit my finger -- again!" by Harry and Charlie Davies-Carr, which is the only non-music video in the list. At number nine is Perry’s “Roar” music video, which one of the three music videos in the list that do not feature a collaboration song. The two others are Psy’s “Gangnam Style” and “Gentleman” music videos.

Psy's latest music video is "Gentleman" and the 37-year-old South Korean rapper has not released any music video since. After “Gangnam Style” and “Gentleman,” he collaborated with Snoop Dogg in “Hangover,” which was not as successful as the first two. Published on YouTube on April 13, 2013, the “Gentleman” music video has been viewed more than 798 million times. Watch it here:
