The 'democratising' Harlem Shake
16 February 2013 Last updated at 10:20 GMT
A year ago a young DJ in New York called Bauer released an electronic dance track called Harlem Shake.
A year on, it is likely to make it into the top five singles chart this Sunday, powered there by an internet dance craze. According to YouTube, 4,000 videos are being uploaded every day of people doing the Harlem Shake.
Radio One DJ Annie Nightingale explained to Today presenter Sarah Montague that "The Harlem Shake can be anything you want it to be. It is the opposite of Gangnam Style, the last big sensation. It is democratising because you don't have to be a great dancer.
She added: "It's not like X Factor. The track has been around for a year and there is a demand for it."
First broadcast on BBC Radio 4's Today programme on Saturday 16 February 2013.
