Navy, we should be more optimistic about FFS' chances. Next week it should enter the BBHot 100 Top 10. If it doesn't reach #1, it's ok, she's still have plenty of material. I will really be proud for a Top 5 peak especially with this kind of music.
But I guess, judging by the Grammys perf, this song has the potential to be an anthem that will makes a stadium sing along. Plus it's very infectious once it hits you.
