Also, i just went looked at the sales, not of that year because i doubt i could find it, but of current total.
Thug Life: Volume 1 (with Thug Life) Released: September 26, 1994 Spot on US charts: 42 US Sales: Gold (500,000)
Me Against the World Released: March 14, 1995 Spot on US Charts: 1 US Sales 2× Platinum (2,000,000)
Ready to Die Released: September 13, 1994 Spot on US Charts 15 US Sales : 4x Platinum (4,300,000)
This means that biggie actually out sold 2 cds of tupac's in about a year, yes it was the thug life album but he was the name with it. Just like junior mafia i am sure outsold the outlawz because people still talk about junior mafia, sadly nobody talks about the outlawz who were all good rappers i my opinion.
Life After Death Released: March 25, 1997 Spot on US Charts: 1 US Sales: Diamond(10,000,000)
R U Still Down? (Remember Me) Released: November 25, 1997 Spot on US Charts: 2 US Sales: 4× Platinum(4,000,000)
Born Again Released: December 7, 1999 Spot on US Charts: 1 US Sales: 2× Platinum(2,000,000)
Still I Rise (with Outlawz) Released: December 14, 1999 Spot on US Charts: 6 US Sales: 2x Platinum(2,000,000)
These are the only cds that match up date wise, not sure what cds you were talkin about though. But you also have to figure that these aren't tupacs most popular albums, although there isn't a tupac song i don't like, these aren't his popular cds. But, even what is in my opinion the best rap cd ever, All Eyez On Me, went 9x Platinum (9,000,000) Biggie had Diamond (10,000,000) With Life After Death, which was his best CD.
