The unofficial King of YouTube with nearly a billion views of his smash hit "Gangnam Style", Psy, has come under fire for lyrics he rapped during a 2004 protest. Some of lyrics read, "Kill those f--ing Yankees who have been torturing Iraqi captives and those who ordered them to torture." Along with the lyrics he also crushed a small American tank replica onstage during the performance.
The protest was in response to two 14-year old Korean girls who were killed when a US vehicle struck them in South Korea.
Psy has since apologized for the incident saying, ""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 by those words."
