R+B star Alicia Keys has taken her new MTV UNPLUGGED album straight to the top of the US charts.

The FALLIN' singer toppled rockers Nickelback with an opening sales week of 196,000.

Elsewhere in the charts, country star GARY ALLAN has something to celebrate at last - his album TOUGH ALL OVER, which was inspired by the suicide of his wife, debuts at number three and Latino pop hunk Ricky Martin's new release LIFE enters at number six.
