was first made available as a free download last Tuesday.
The song is the band's first single from new album Viva La Vida Or Death And All His Friends, which comprises 10 tracks produced by Brian Eno and Markus Dravs.
Coldplay's website was hit by technical glitches when the song first went online, because of the huge demand.
A spokesman for the band said: "In the past seven days the single has been downloaded for free by a staggering two million people.
"It would have outsold the whole of last week's top 40 (singles) four times over."
The album release on June 12 follows the success of the album X&Y, selling 10 million copies since its release in 2005.
Violet Hill is released commercially today (Tuesday).
