^She usually releases 4 singles off of each album. BOMT had 4 in the US, 5 overall, Oops! had 4, Britney had 4 in the US, ITZ had 4, and Blackout only had 3.
So I'm not sure how many singles her label will put out, but I think this could be her best era singles-wise.
I love Mannequin, but I really feel like her label would choose "Kill the Lights" over it. I love both of them, so idc which one she releases, if she even releases them. I say she goes for 5 or 6 singles.
