On "Desperado," the second song on his brand-new Madadelic mixtape, Mac Miller offers this summation of where his career stands: "Running out of paper, writing on my hands / Hundred thousand haters writing about my jams." So it goes when you're a 20-year-old MC with a No. 1 album under your belt, but this Pittsburgh rhymer isn't sweating the critics.

As Macadelic -- available for free download here -- unravels, Miller keeps the focus on himself, spitting lines about love, drugs, money, fame and other subjects that have likely become increasingly vexing since his Blue Slide Park topped the charts last November.

"It's like the story of someone who is growing up, trying to figure out who he is and trying to figure out what he's supposed to do in the world and how he's gonna change it," Mac said in a recent interview with MTV's Mixtape Daily. "I think it's a great piece because it's a great part of my career, it's a great time right now and I feel like I been making mixtapes for five years, so this one is very special to me."

Making it even more special are the guest spots from Lil Wayne, Cam'ron, Kendrick Lamar and Juicy J, among others.
