The hit single "Happy" by American record producer and singer Pharrell Williams has been declared the most-downloaded track ever in the UK, The Independent reports.
British music sales tracker The Official Charts Company announced the feat and said the song has taken the place of American-Canadian singer Robin Thicke's 2013 track "Blurred Lines," which Williams also produced and featured on.
With "Get Lucky," Williams' 2013 collaboration with French electronic music duo Daft Punk, being on the sixth spot, the singer is also the only artist to have three songs on The Official Charts Company's top 10 most-downloaded tracks list.
The firm announced the news as it was celebrating its 10th anniversary.
According to the company, "Happy" has sold 1.62 million times in the UK since it was released in June last year, while "Blurred Lines" has sold 1.59 million times. "Get Lucky," meanwhile, has been downloaded 1.4 million times.
As all three singles sold more than 1 million copies each within a year, Pharrell has also become the second artist to reach the feat, with iconic rock band The Beatles being the first, according to The Guardian.
Also on the list are Adele's "Someone Like You," which is on the third spot with 1.53 million copies sold, and songs by Maroon 5, Gotye, the Black Eyed Peas, Avicii, Rihanna and Kings of Leon.
A message from Williams appears on the website of the company, which says: "I would just like to thank you, first and foremost, to the people, because the charts are determined by them. I have a lot to be thankful for because they've chosen these things and it's resulted in 'Happy' being what it's become."
The song was released in last year as part of the soundtrack for the animated film "Despicable Me" and eventually on William's second solo LP "G I R L."
"Few artists of have ever dominated an era as he has done over the past 18 months - he is a true phenomenon of our times," said The Official Charts Company CEO Martin Talbot, as quoted by Hollywood Reporter.
