The album also cemented Biggie's legacy as one of the all time greats in the hip hop genre. It was certified 10 times platinum (diamond) approximately two years after its release, making it the highest selling rap album of all time.
I was wrong about it going 20 somethin mil...but he still went diamond

The Marshall Mathers LP (2000) #1 US (8 weeks) (9X Platinum); #1 UK (6X Platinum) - 17 million worldwide
And again I was wrong about MMLP going 30...but these stats were made most likely 2002 or 2003...so think about how many more sales its gotten since then...maybe not a lot but it still adds on
either way they both went diamond
Goodnight
peace
