That's part of the problem. Hitting the same tone, the same lyrical ideas, over and over is pointless. He put out over two hours of this in a year - he should be moving on. The production on "kiss Land" is basically ruined because he took a great beat (used by main attraktionz on "nothing gonna change," check it out) and added useless, compromising drums and basically killed the beat. The lyrics are becoming more laughable with each passing song, almost as if he's diving into a self-parody of what made the first three mixtapes so compelling.
I'd also argue those mixtapes have already begun to fade, especially in the rereleased form of Trilogy. They're good, but I haven't listened tot them in over six months and I don't really feel a need to.
