Hancock's Great Grammy Bounce

You've heard of a Grammy bounce. This is more like a Grammy rocket.

Herbie Hancock's Grammy-winning album has seen a huge sales spike since it captured the top album at the event a week ago Sunday.

Nielsen SoundScan reports "River: The Joni Letters" posted an almost incomprehensible 967-percent increase.

Sales last week were 54,000 -- which should give you an idea just how few copies had been sold before the Grammy win.

Also showing a Grammy-related spike are albums by Kanye West, Amy Winehouse and Foo Fighters.
