Korean hitmaker Psy has revealed that despite becoming the first artist to reach 1 billion YouTube views, which he achieved with his single 'Gangnam Style', he hasn't profited from the track at all.

Speaking to Kiss FM, the singer explained that he has been waiting on royalties from his record label since the song was released and is getting impatient with having not been paid for it yet:

"Collecting money from more than 100 countries with iTunes and publishing and everything else takes a long time. I'm still waiting right now. Universal! Universal! I'm still waiting."

'Gangnam Style' was also featured on hit U.S. series 'Glee' and is known globally thanks to its easy-to-learn dance routine.
