Psy Says Releasing 'Gentleman' Was 'The Worst Time Ever' 'That week was like hell' Psy says of releasing his record-setting follow-up to 'Gangnam Style.'

When Psy released his brand-new single "Gentleman" earlier this month, he didn't really have time to think about the daunting task of following upone of the hugest hits of all time ... shoot, he didn't really have time to think about anything.

"I released it on April 12, and on April 13 I had a huge concert in Korea ... so that week, it was like hell," he told MTV News. "On Friday, I had to release the single, and on Saturday, I had to release the video, and I had to do a 50,000-person stadium concert. And that same week, on Monday and Tuesday, I did the shooting [of the 'Gentleman' video]. And I was done with the shooting on Tuesday, and on Wednesday, Thursday, Friday, we were editing, and I was rehearsing and I was memorizing all the choreography. So that week was like the worst time ever in my life."

Psy Had The 'Worst' Week Ever Because Of 'Gentleman'

Of course, we suspect his outlook improved slightly in the days following the premiere of "Gentleman," as it shattered the record for most YouTube views in a single day, and, in just two weeks, has racked up a staggering 230 million views in total. Sure, it's still got a ways to go before it can catch the billion-plus views of "Gangnam Style" but Psy's biggest fear has already been vanquished: No one can call him a One-Hit Wonder anymore.

"I honestly changed this song so many times until the very last moment. I was not excited, I was terrible; I was so nervous," he said. "My only goal was to avoid being called a One-Hit Wonder. So that was a very nervous moment right before the premiere; and in two weeks, with 230 million views, I'm not a One-Hit Wonder. I'm really happy and relieved about that!"
