Jay Sean - Down
Since 2003, Jay Sean has had a string of hits in the UK but his biggest success to date is his new single, 'Down'.
'Down' is the first single to be taken from his third studio album, 'All or Nothing' and it's the first single the star has released in the US.
Until Jay Sean came along, the Black Eyed Peas had dominated the US chart, their single 'Boom Boom Pow' and 'I Gotta Feeling' have held on to the top spot for a total of 26 weeks.
In topping the US chart, Jay Sean has become the first British act to score a Billboard Hot 100 No. 1 since Coldplay with 'Viva La Vida' last year.
