Sean’s single Down, which features rapper Lil Wayne, has sold a million copies and been at number two for the past three weeks.
Sean, from Hounslow, west London, is now the most successful male UK urban artist in US chart history.
“If you have some good music, you can make it anywhere,” he said.
The singer is currently enjoying greater success in the US than he has found at home.
The former medical student had two UK top 10 hits in 2004, but later split with his record label Virgin when, he says, they tried to make him sound like James Blunt.
He went on to form his own record label Jayded with his management company 2 Point 9, and the resulting music attracted the attention of US hip-hop label Cash Money, home of Lil Wayne.
The singer had already written and recorded the song Down when Cash Money paired him up with Lil Wayne, who had the best-selling US album of 2008.
Lil Wayne added a 30-second rap to the track and the collaboration was propelled toward the top of the charts.
“I’m very blessed that it got off to a flying start and it’s been doing crazy things over the last couple of months,” Sean told BBC News. — BBCOnline.
