Hot on his heels are T.I. and Justin Timberlake with their pairing on "Dead And Gone," which hip hops from number nine to two.

Veterans Eminem, Dr. Dre and 50 Cent slide a little to the number three spot with "Crack a Bottle" while

Kanye West logs his 15th week on the download chart with "Heartless" in the number four position. The seemingly indestructible "Just Dance" from Lady GaGa and Colby O'Donis hangs tough at number five for its 28th week on the chart.
