MusicRadar notes: "And for Coldplay, the stats keep getting better and better: their 2008 release Viva La Vida, is now ranked as the top-selling digital album in SoundScan history. (Although we suspect a certain king of pop might stand a chance at besting that figure within a matter of weeks.)" So Coldplay's achievement here may be surpassed by Michael Jackson pretty soon, which would make sense.
Does this surprise you at all? Or does it seem natural that Coldplay would be the first band to sell over a million digital albums?
