I mean, I know the song is slow and people are worried it might not be a hit, but what about Teenage Dream, Firework, Grenade, those all hit #1. And for first singles? Just The Way You Are hit #1 and it has the same vibe as Mr. Know It All. I know it's a risk, but it's something you have to take in the industry. Either way, I can see the single being a hit, even if it doesn't hit #1.
