As for the retiring thing, he announced his next album like a day after this one dropped and is claiming it'll be his last. I kind of doubt that--most of the time rappers say they'll retire it's an attention grab--but we'll see, I guess.
And @ littlebirds, I've always thought he was pretty much an average rapper who got overhyped. Honestly how I see it is that he built a super dedicated fan base through his mistakes and first album by people labeling him as a top-notch lyricist and a leader of "conscious" hip hop. But to me he hides his average lyrics by rapping fast as hell all the time and most of his "conscious" elements are either surface level or pretty mixed messages. Overall I think he's just OK.
