Nouvago investment Perfect Storm Music Group hits Billboard hot 100 nr.1

Kelly Clarkson tops the Billboard Hot 100 songs chart with "Stronger (What Doesn't Kill You)".

In what an RCA Records representative terms a "perfect storm" of radio airplay, digital sales and pop culture prominence, Kelly Clarkson's "Stronger (What Doesn't Kill You)" rises from No. 2 to No. 1 on this week's Billboard Hot 100 songs chart.

The uptempo pop anthem becomes the original "American Idol" champion's third leader on the list.
