Number 1

According to Billboard.com:

"This Is Why I'm Hot" by Mims is the new number 1 on the billboard hot 200. In fact, since the song went from 32-1 that makes it the third largest leap in the chart's history and the first No. 1 single for Capitol Records since 1992. The track bows atop the Hot Digital Songs chart with 135,000 downloads and trails only Kelly Clarkson's "A Moment Like This" (52-1) and Rihanna's "SOS" (34-1) for biggest jumps in the chart's history.
