For me, Gaga's ratio is bigger and more impressive.



I didn't know Where Have You Been sold less than You And I

Gaga preparing ARTPop, it's inevitable domination. Rihanna extending her #'s w/ Diamonds & Stay.
Good job for both

Edit: Oh wait, these are solo & Diamonds is already there.

Gaga.

Originally posted by RihLORD's #1 Stan Omg, she's done 40m singles in the US already?!

She is at 90+ millions WW, no surprise for the US, but it is titanic numbers for a 4 years run. She has five 9 million sellers WW, 3 of them having topped the 10 million mark.

Both

Originally posted by stronger23 why add "take care" but not "run this town" or "live ya life" for rihanna?

Originally posted by umichgrad07 Take Care isn't hers.

Originally posted by ALPHA The 58 was with all her collabrations (Eminem, Guetta, ...) Diamonds is counted in the OP already and why should he count sold album tracks when it says single success? You're one of the navy members that do too much

Originally posted by Liberdade mi amor Sorry, didnt notice, I will edit it out. Dr. Cake I will update the OP, Thanks. Gaga will soon have two 7 million sellers

The receipts you first wrote in the OP where taken from the report published on January 1st. The ones I gave are from the beginning of February and late February (for Poker Face).
