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.''
