Singer Psy said he followed the advice of his manager, as well as a U.S. famous producer, Scooter Braun to add Korean rap in his new song.

In a recent interview with Associated Press, Psy said, "There are a lot more English lyrics than Korean. Snoop Dogg agreed at once when I told him the title of the song, 'Hangover.' No one except Koreans really understand what I was saying. I should try harder to reach out more."

Then Psy added, "But Scooter Braun told me to add Korean lyrics. He told Psy that what makes him unique are his Korean lyrics, otherwise there are plenty of good rappers in America. He added that Psy was smart and could accomplish it."

Psy added, "Braun has a strong resistance to alcohol of all the Americans. Asians mix a lot of alcohol drinks and drink on a daily basis. So I knew that Brown was a strong drinker when I met him."

Psy's MV 'Hangover' recorded over 40 million views after just three days of being released.
