Kelly Clarkson performing live at Palladium. Cologne, Germany - 03.04.08

The American Idol winner's latest offering, All I Ever Wanted, was due to hit stores on 10 March (09).

But staff at the Norway division of Apple's iTunes accidentally put complete tracks available for download on its website on Friday (20Feb09) - and now the songs are spreading across the net.

It comes just hours after U2's new CD No Line on the Horizon was prematurely offered on a digital music service run by Universal Music Groups Australian division, ahead of it's 27 February (08) release.
