The music video of South Korean rapper Psy's latest single "Hangover" was the most viewed K-pop clip on YouTube this year, the global video-sharing site said Tuesday. 

The song, debuted in June and featuring U.S. rapper Snoop Dogg, is a follow-up to Psy's international hit "Gangnam Style," which has drawn more than 2.1 billion world views and prompted YouTube to upgrade its viewer count system since the number of clicks went over the bounds.  

The exact figure for hits on the video clip is not available for public disclosure, YouTube Korea said, citing company policy. 

"Overdose" by Exo-K, a subgroup of a Korean-Chinese boy band Exo, came second in the ranking.  Exo's hit "Miracles in December" also made it to the top 10, YouTube said. 

Girls' Generation, a group of eight that gained immense popularity at home and Japan, was placed third in the most watched list with "Mr. Mr.," the title track in its fourth mini album released in February. 

Four-member girl group 2NE1's "Come Back Home" came in fourth, and "Touch My Body" by another popular girl group Sistar ranked ninth on the most viewed K-pop chart. 

The most viewed South Korean channel on YouTube was SM Town, the biggest entertainment agency in the country, followed by Psy and KBS World TV, the English channel of the namesake public broadcasting company. 

The compiled data, released every year, are based on the hits made from Dec. 1, 2013 to the last day of November this year, YouTube said. (Yonhap)
