Not only did she get a massive AI gain on POP, she also saw a huge increase in spins. This means that it's not just Z100 putting it into power rotation that caused this huge update. It helps that the week of rolling effects is just now over today.
I still can't get over how well this song is selling. I knew it would be a big song when it leaked way back when, but I wasn't expecting this. I thought it would be the lead single. It's just crazy how it hasn't really had tons of big promo (X Factor and then an SNL performance are big I guess but I don't attribute her sales to either of those. SNL helped boost it but that's about it!) This song has taken off like a lead single!! Hell, maybe even better than that. Man, if she doesn't get this Hot 100 #1 at some point (hopefully this coming week) I'm going to be SO pissed.
