Hip-hop sensation Soulja Boy has claimed a second week at the top of the U.s. pop charts as the top four singles in America remain unchanged.

Crank That (Soulja Boy) hit the top spot last week and still reigns ahead of Kanye West's Stronger, Fergie's Big Girls Don't Cry and The Way I Are by Timbaland.

T-Pain's Akon collaboration, Bartender, jumps up a spot from six to five.

Alicia Keys' new single, No One, is this week's highest debut, entering the Billboard countdown at 71.
