He's sleepwalking through most of the verses here. Because honestly, "I know we facin' a recession / But the music y'all makin gonna make it the great depression," is a lame ass line. But like he says, this ain't meant for iTunes. This is a public service announcement. He's pretty much saying, "Hey guys. Grow a pair." And I can respect that.
There's not much else to say about "D.O.A.", really. It serves it's purpose by making it known that auto-tune is over and Jay-Z still exists. Whether or not this actually does kill auto-tune is an interesting question, but frankly, if I had Jay-Z calling me out on my lack of balls, I'd probably shut the fuck up and start rapping again.
