I can't believe the #15 on Kworb is over 0.5!

I don't think I've ever seen anything like that before.
That's bad for Rihanna, since her sales only need to halve and she's dropped all the way out the top 15. I'm impressed that she's still #1 on iTunes (uncombined obviously), but today might be her last day (unless she gets another boost in the future).
