Having already unleashed one song online, the Rap supergroup known as CRS (Child Rebel Soldiers), consisting of Lupe Fiasco, Kanye West and Pharrell Williams, is hoping to find time to cut an entire album. Their one song, "Us Placers," samples Thom Yorke's "The Eraser" and was performed by Fiasco at Lollapalooza a few weeks ago.

"Now [our labels are] working it out," Fiasco tells Billboard.com. "Whoever is going to pay is going to pay a whole hell of a lot. Everybody is excited, [but] 'Us Placers' is the only record we have."

Meanwhile, Fiasco has pushed back the release of his sophomore album, Lupe Fiasco's The Cool, from October 30 to November 20 as he continues to perfect the effort. And despite his status as an up-and-coming talent, the rapper says he is going to stop releasing mixtapes and may not even do that many more studio albums.

"I'm just wearing down," he told Billboard. "I'm never doing mixtapes again, not even Internet ones. My whole energy for making hip-hop music is slowing down. I've been doing it for seven years. I still don't think I'm famous. I'll do what I have to do to promote my next album, but I'm not enthused about doing seven albums. I'll do my three, and then I am going to keep moving to the next phase of life and maybe grow trees."
