G.O.D. 

According to the interview on allhiphop.com , published Dec 1/09, the last two projects of AZ are not his studio albums.

ahh: "(...) you released “Legendary” early June of this year…..tell me about that project."

AZ: "That was just a mixtape, as you can see I didn’t promote, no videos…..it was just a mixtape I put out. The last album that I put out was “Undeniable” in 08. Right now I’m working on Do or Die 2."

That's why I think both "Legendary" and "G.O.D." should not be considered his studio albums.
