No, a performance would push the song back again. And video is was passed it's peak? the song still gets 2.1 M views per day, and it's in the top 10 most watched videos on vevo. And now with Sugar, TOL and LMLYD falling, a performance would push it to a new peak.
You're just wrong
No, he's not. The song is decreasing hard on radios. 2.1 million views per day is not that much and it's far from enough. Yes, top 3 peak is possible but there are too much factors going against it. It's kinda pointless to discuss a #1 peak.
Rihanna hasn't promoted FFS for 2 months, she may perform it this Saturday but that's it.
I thought maybe she could perform FFS along with BBHMM on SNL when the album is out but it probably won't happen since a new single will probably drop before the album / along with it.
