Despite having been lauded for his bizarre and amusing song and video 'Gangnam Style', Psy may have perhaps ruined his entire career in the USA, after it has been discovered that eight years ago he performed a song which spoke about killing men, women and families in America, reports MTV

The track, which was a collaboration between Psy and Korean rock group N.E.X.T, was called 'Dear American', and included lyrics such as "Kill those f***ing Yankees who ordered them to torture... Kill their daughters, mothers, daughters-in-law and fathers... Kill them all slowly and painfully." 

Psy has since explained the context of the song, and accompanied it with an apology in a statement:

"As a proud South Korean who was educated in the United States and lived there for a very significant part of my life, I understand the sacrifices American servicemen and women have made to protect freedom and democracy in my country and around the world. The song I was featured in -- from eight years ago -- was part of a deeply emotional reaction to the war in Iraq and the killing of two innocent Korean civilians that was part of the overall antiwar sentiment shared by others around the world at that time. While I'm grateful for the freedom to express one's self I've learned there are limits to what language is appropriate and I'm deeply sorry for how these lyrics could be interpreted. I will forever be sorry for any pain I have caused anyone by those words."

"I have been honored to perform in front of American soldiers in recent months - including an appearance on the Jay Leno show specifically for them - and I hope they and all Americans can accept my apology. While it's important we express our opinions, I deeply regret the inflammatory and inappropriate language I used to do so." He concluded, "In my music I try to give people a release, a reason to smile. I have learned that though music, our universal language we can all come together as a culture of humanity and I hope that you will accept my apology."
