In a sea of pretty pop stars, a chubby, rapping dancer may not be the usual K-pop hit.br br But an unconventional South Korean has found himself turned into a viral sensation.br br Psy is the latest musician to have an internet hit.br br In just under a month, his music video "Gangnam Style" notched up over 20 million views on YouTube.br br While he's been a local musician for a decade, Psy says he never expected to break overseas.br br Even now, he admits he's an unlikely role model.br br SOUNDBITE: SOUTH KOREAN SINGER PSY SAYING (Korean):br br "I have been looking for fun my whole life. You may think it's sad, but that's the aim of my whole life. If I hadn't become a musician, I would most likely have been a loser. I was very lazy - just liked drinking, night clubs and girls."br br The performer is not without controversy.br br While landing in hot water for antics off-stage, his performances are also unusual.br br Fans packed in to a South Korean stadium were recently treated to a Lady Gaga parody, complete with pyrotechnics.br br Psy will perform his first concert in Japan this September.
