I dont think any artist should just be measured on the amount of stuff they've put out, but rather on the quality - and of coz, on how the ppl receive it...
Wayne has had 2 albums that meet the above criteria ... and none on them have had the type of impact that All Eyes on Me, for instance, has had on the people. Weezy still doesnt have his equivalent of monster album like Doggystyle, Ready to Die, Illmatic or even a Reasonable Doubt ... the Carter 2 might reach that status, but that is yet to be seen..
