Pharrell Williams' song Happy has overtaken Robin Thicke's Blurred Lines to become the most-downloaded track of all time in the UK.
The US singer and producer is the only artist to have three tracks in the top 10 most-downloaded songs chart, beating artists including Adele and Calvin Harris.
His collaborations Blurred Lines and Get Lucky have entered the chart at number two and six respectively according to figures from the Official Charts Company.
Happy has sold more than 1.6 million copies since its release last June after featuring on the Despicable Me 2 soundtrack.
Other big sellers include Adele's Someone Like You which is the third biggest-selling download of all time with 1.53 million downloads and Maroon 5's Moves Like Jagger which is fourth with sales of 1.47 million.
