A lot of people think Tha Carter IV is Lil Wayne's worst album, and a lot of people were shocked when it sold close to one million copies in its first week of release. They shouldn't have been, and certainly no one should be surprised when I Am Not A Human Being II puts up massive sales numbers, as well. It's already the No. 1 album on iTunes, across all genres. Wayne is a pop culture fixture, and much of his fan base isn't even privy to the criticisms that have been leveled at him during this latter portion of his career.
The album is still going to sell a ton of copies.
