There are sure to be a few features on J. Cole's debut, Cole World: The Sideline Story, but none more anticipated than the one between him and his Roc Nation CEO, Jay-Z. Cole has been tight-lipped about the details surrounding his album, which is slated to drop September 27, but he did open up to MTV News about his and Jay's collaboration, which is still in the works.

Jay snagged the young spitter for a verse on his "A Star Is Born" track off of 2009's The Blueprint 3, and now Cole is waiting for Jigga to return the favor. He won't reveal the song's title just yet, and Jay hasn't even finished his verse, but after he made the beat for the song at his home, Cole knew he had something worthy of Hov's attention.

"I actually did the song thinking I would just throw it out when I made it," the Fayetteville, North Carolina, MC said of the track, which he originally intended to offer to his fans as a free download. "I made it in my crib and I was like, 'Man I'm gonna throw something out today, or tomorrow whatever, let me do a song.' Then I started making it, and as soon as I made it, I was like, 'Oh nah, nah.' "

The instrumental came out so good that Cole scrapped his original plans and immediately began to pen his rhymes. "I had already wrote the verses and I realized, 'Man, this is for Jay.' I finally made a song that was perfect for Jay," he said backstage at last week's date on Rihanna's Loud Tour.

During his appearance on "RapFix Live" back in February, Cole explained to Sway the high standards that he holds for the track. "They been asking me this for a while because I said he was like one of the only rap features I wanted, but it's about the song. It's a lot of pressure on that song. I feel like that's my hardest song to make, is the one I want Jay for. My standards are so high," he said.

In an effort to hold on to album details as long as he can, Cole wouldn't say much more about the song, but did reveal that he left a message for his fans buried in the track's hook. "When people hear the hook, it's kind of like a message — I could be talking to a woman, to my girl, or to my fans or to friends," he said. "But it's really a subliminal message to my fans in that hook."
