In a period of cooling tensions around the Korean Peninsula, North Korean officials have rejected K-pop superstar Psy entry to the country to perform in an upcoming concert in Pyongyang. 

"Details have yet to be confirmed over whether Psy, who ascended to global stardom with his hit song "Gangnam Style" in 2012, will join the troupe. But local reports said the government offered to bring Psy to Pyongyang, but Hyon Song-wol, the regime's star singer and the leader of Samjiyon Orchestra, rejected this.

Hyon reportedly declined the proposal as Psy's free-spirited performances contrast to the sentiment of North Korean citizens."
