The Grammys will be a wildcard in all of this. We haven't gotten a full list of performers yet, but ballads tend to go over well when performed at the ceremony (see Stay from last year). If SS is performed there, it's highly likely they'll go back to #1 on iTunes and snatch the Hot 100 #1 due to the boosted sales/streams.
I hope she performs it at the PCA's and the Grammy's, the song deserves #1
