Manager Scooter Braun believes the key to viral sensation Psy's popularity is his ability to make people dance and have fun.
Psy is so successful because he's good fun.
The South Korean rapper's music manager Scooter Braun thinks - who is also partly responsible for Justin Bieber's stratospheric rise to fame - believes the 'Gangnam Style' hitmaker has become a global sensation despite not singing in English because of the hilarity of his dance moves.
Scooter told MTV News: ''People love to watch that guy dance. It makes people have fun, and I think music should be a release.''
Psy's second international release, 'Gentleman', has racked up 224 million views since April 13, which Scooter - who signed the rapper to his label School Boy Records last year - believes could catch up to his 1.5 billion views for 'Gangnam Style' if he keeps making people laugh.
Scooter said: ''It went like Number One [in the video chart] in, like, 52 countries, so it was kind of mind-blowing for us. But he's just fun.
''And I think he's coming to the US at the end of this week to start performing it on TV, and around the world.
''And he represents having a good time, so good for him.''
The viral superstar previously said he hoped his second single would prove just as popular as 'Gangnam Style' thanks to his fun adaptation of a traditional Korean dance.
He recently said: '''Gentleman' is another very rousing song... The dance is one known to all Koreans but new to foreigners. This will be presented in PSYstyle.''
