Katy Perry's 'Roar' has sold a quite good 557,000 downloads in America in its first week on sale and has risen 83 places to Number 2 on the main Billboard chart.
According to Billboard, this makes it the "sixth-largest sales week for a digital song ever, Perry's own best sales week and the biggest for her label, Capitol Records."
New at Number 3 on the Digital Songs chart is Lady Gaga's 'Applause' with sales of 218,000, which is quite disappointing really. The single enters at Number 6 on the Hot 100.
Robin Thicke is still at Number One after ELEVEN BLOODY WEEKS.
