needed: hip hop sales rankings per year

[Dante]

got a bet going that i need to win... i thought it would be easy to find the top 25 or even top 50 or so hip hop albums by sales (or even opinion) per year for at least 1990 through now. no luck. anyone have any idea where i can find info like this?

nah that shit is hard
I dont even think findin the top 25 or 50 Overall per year would be easy

edit
billboard has year end charts that go back not sure 2 what extent they are for each year but should be able tof ind shit on their website.or at least be able to order the information
