Timbaland and Kanye West have lost the U.s. pop chart battle with Soulja Boy for yet another week after the rapper's Crank That (soulja Boy) hit scored a sixth week at number one.

The hip-hop anthem saw off a challenge from Britney Spears last week, but her Gimme More slips from three to six on the new Billboard Hot 100 countdown.

West, who spent a week at the top with Stronger after briefly toppling Soula Boy last month holds on to the number two spot, while Timbaland's Apologize jumps up a spot to three.

Alicia Keys' No One climbs up four spots to number four and singer/songwriter Colbie Caillat's Bubbly rounds out the top five.

The highest debut on the new chart belongs to country star Sara Evans - her As If enters the countdown at number 74.
