Beyonce begins 2009 with a fourth week atop the Billboard Hot 100. Lady GaGa has also earned a great New Year surprise as her hit single “Just Dance” featuring Colby O’Donis moves from 3-2 with nearly 419,000 downloads, a feat only topped by FloRida’s hit single “Low”. For the first time in several weeks, T.I. and Rihanna’s massive hit “Live Your Life” falls from the top two. The single, which was originally released early Fall is now at no.3.
