I agree with Roman Holiday & Seba. Lead single released 2 weeks before album release date, with a radio deal. To top things off, debuting the video the day the single gets released.
If Nicki does this, the lead single would easily debut in the Top 10
I've also noticed that songs get huge boosts when the album is released (Work, One Dance), but Nicki never has any hits out by the time her album is released.
