Robin Thicke's 'Blurred Lines' is the most downloaded song of all time in the UK.
The track comes ahead of singer Adele's Grammy Award-winning ballad, 'Someone Like You', which has been bought 1.53 million times.
Robin told OfficialCharts.com: ''I'm so honoured, the success of 'Blurred Lines' is a dream come true.''
Official Charts Company executive Martin Talbot added: '''Blurred Lines' is surely one of the catchiest pop hits of all time, so its success is no great surprise. But to become one of only two tracks to have been downloaded 1.5m times - and climb to the top of the poll as the biggest download of all time - is an incredible achievement.''
Other songs which are among the UK's most downloaded include 'Moves Like Jagger' by Maroon 5 and Christina Aguilera, 'Somebody That I Used to Know' by Gotye and Kimbra, and 'I Gotta Feeling' by the Black Eyed Peas.
The countdown was compiled to celebrate the tenth anniversary of legal downloads contributing to the UK charts.
