Why not?She's gaining way faster than they are falling, even if they will keep on falling like 1m a week [which they won't cuz' they already losing ground on Rhythmic] she's gaining like 10m a week, with just under 20m difference she will get that one spot in 2 weeks or even less IMO.
1. BLACK EYED PEAS - Boom Boom Pow = 112.800 (- 0.932) =
2. KERI HILSON - Knock You Down = 101.432 (+ 2.148) =
Keri will most likely be taking over the #1 spot soon enough. It doesn't matter if its featuring other artists or not. Most of the ones mentioning features are stans of artists that have features on most of their hit singles as well.
