YouTube sensation Psy is on course to become the first South Korean star to make the UK top 10 - and is threatening to become a surprise number one.
The video for the rapper's single Gangnam Style has been seen more than 227 million times and the track has made it to number one on the UK iTunes chart.
Now with a surge in sales as the track gathers momentum thanks to a curious dance, it has a possibility of topping the charts on Sunday.
The Official Charts Company said today it is 22,000 copies behind The Script and Will.I.Am's single Hall Of Fame, based on the latest data. But sales have been rising by an average of 20% each day as more people become aware of the song, whose video features the 34-year-old dancing as though he were riding a horse.
The track broke into the top 40 on Sunday, at number 37, four weeks after its release, and has been climbing steadily throughout the week and latest sales figures put it at number six today.
Psy, who is already an established star in South Korea having released six albums, taught Britney Spears his dance on US TV show Ellen last week.
The new chart will be announced on Sunday.
