THO 100 Update for the week ending January 23, 2010

Since the TopHitsOnline chart began seventeen years ago, there have only been 10 songs to stay at #1 longer than 10 weeks. Lady GaGa's current #1, "Bad Romance" is one of them. This week the song holds off hits from Ke$ha and Owl City to remain on top. "Romance" still has a large point lead, which means that the all-time THO record of 15 weeks at #1 is in jeopardy. That record is held by Cher with her hit "Believe" (1999) and Madonna with "You'll See" (1995-1996). Madonna's "HungUp" is the most recent song to spend more than ten weeks at #1, in 2005-2006. On the current chart, GaGa's "Telephone" moves back into the top 10 as does Alicia Keys' "Try Sleeping With A Broken Heart." "Replay" by Iyaz has the chart's largest point gain.
