Then you'd realize that as soon as Katy's next single comes fast, her previous singles fall even faster. It's not rocket science. You can check the previous AirPlay threads from 2010-2012. It's quite normal.

I'm thinking it could reach that threshold after the Christmas freeze is over.

Best male & female artist of our generation. BTW, I love your avatar

Lol Gorilla did great.
60M+ AI for a song with ''You and me ****ing like gorillas'' as the chorus is more than good.
+ its not like it was doing spectacularly on iTunes to warrant higher airplay, anyway.

ONEREPUBLIC - Counting Stars: 43.078 (+ 1.212)

Roar is holding REALLY great. The fact that it peaked so high and fast (and not really decreasing THAT hard) + she already has another song with 40m (and DH lingering outside the Top50 on Pop)

Her insane radio power
