Rihanna - 150-200k
BEP - 300-450k (depends on the 1st single)
Taylor - 700-750k
Susan - 650-750k
Kanye-300-450k
Nicki-100-150k
(No shade,but Rihanna's doesn't stand a chance infront of Boyle's 2nd week )
i think nicki will have higher first week sales than rihanna nicki will do atleast 200k+ in my opioin i mean i dont think singles have alot to do with anything seeing how welll katy singles did and how her album didnt sell that much think of all the promo and high chartings songs katy had and what did she do trust me i think nicki can outsell kanye too the girl has hype so drake can sell 450+ first week but yall dont think nicki can do at lease 200k her fanbase is a good size and pretty dedicated ......nicki will do big numbers for a female rapper anyway
