THO 100 update for week ending December 19, 2009

The last THO chart of the year sees the return of one of THO's biggest artists over the past decade: Jennifer Lopez. Her latest single, "Louboutins," has the highest debut, besting new entries from Pearl Jam, Allison Iraheta, and Three Days Grace. We last saw J-Lo briefly in early 2008 with her single "Hold It, Don't Drop It," which only made it to #31 on the chart. The last chart of 2009 also has Lady GaGa's "Bad Romance" on top for a sixth week. Next week's chart will be frozen, as it always is, so Miss GaGa will sit tight for a seventh week. Instead, look for our 2009 year-end chart due soon.
