Alicia Keys had plenty of reason to be thankful on Thanksgiving (22Nov07) - her song NO ONE knocked Chris Brown's Kiss Kiss off the top of the U.S. singles chart. Keys, who is also currently number one in the U.S. albums chart with As I Am, climbed a place to take pole position from Brown, whose Kiss Kiss falls to two. Timbaland's Apologize sits at three, while Flo Rida's Low featuring T-Pain moves up two places to four. Soulja Boy's mega-hit Crank That (Soulja Boy) drops a position to five. Celine Dion scores this week's highest debut - her Taking Chances enters the chart at 54.
