"I Wanna Go" won't fall out as long as #11 is falling the same or more.
"IWG" just fell -0.0007, while "Good Life" (#11) fell -0.0013. And they are 0.0109 in overall difference. Brit's fall is also a lot smaller than the last update, meaning she's going stable or might gain soon. Basically she's safe.
We also have Drake's "Headlines" falling fast. "IWG" will claim another victim to save itself.
We've rid of "Rolling In The Deep", "Give Me Everything", and "Super Bass" in the last week or so.
