I'm confident we will hear the song in full before the end of this week. She isn't going around the U.S. just to play music for fans for these listening parties. I'm sure she's going to radio stations and they're going to give the track a few spins before the release which may be this Friday.
POP SINGLE HERE WE COME!
I hope the album offers something experimental like her mixtape/EPs, too 
thats where the worry comes
