THO 100 Update for week ending January 17, 2009

Lady GaGa makes a surprising jump from #6 to #1 on the THO 100 this week. Her smash hit "Just Dance" (featuring Akon & Colby O'Donis) benefits mostly from increased airplay and single availability in the UK, although radio airplay in many parts of the U.S. is still growing too. This is Lady GaGa first THO #1, and in fact her first THO hit. It replaces The Killers "Human," which ends up spending only a single week at the top. "Human" is just barely behind "Just Dance," so a re-entry into the top position next week would not be a surprise. Elsewhere on the chart, Pink and Girls Aloud have new songs enter the top 10, and Ne-Yo and The Fray move inside the top 40 with new singles.
