Songs that leaked from Dr. Dre’s Detox recording sessions earlier this year revealed that Nas and R. Kelly are among the artists in consideration to appear on the long-awaited opus. And T.I., Lil Wayne and Drake are among the MCs believed to be ghost-writing for the album. But if Dre gets his way, a certain renowned Brooklyn rhymesmith will be pulling double-duty on Detox, both writing and delivering a guest verse.

“Well, actually, Jay-Z’s just been in the studio doing some writing,” Dre told MTV News on Friday while promoting his new Beats by Dr. Dre/ HP notebook collaboration. “Hopefully I’ll get him to perform on the record. Jay, come holler!”

Detox is the follow-up to Dre’s 2001 album and will complete the trilogy that began with 1992’s The Chronic.

In May, a snippet of a Detox track was released on a Dr. Pepper commercial that features Dre. The song, tentatively titled “Sh– Popped Off,” features production similar to a track that leaked in February with Tip referring Dre.’s vocals. “It’s the D.R. … Made the West side worldwide, no PR/ Gangsta-rap God, I’m the end-all, be-all/ California love from the Bloods to the C-Dogs.” Earlier this month, Dre told ABC News he’d like to finally put the finishing touches on Detox by the end of this year in time for a 2010 release. “Hopefully, I’ll get it done at the end of this year, and we can hear it next year,” the normally press-shy producer said.

Snoop Dogg talks about the recently released picture of him, Dre and Game sitting in the studio. Working on Detox -the long anticipated Dr. Dre album- to be exact. In an interview, Snoop Dogg said it was all about “Symbolizing the West Coast movement.” He also said they have been in the studio for about 2 weeks before Snoop came up with the idea of calling the Game. “I came and called Game up so he could come and be a part of this particular record that Dre had that was needing his vocals and needed his assistance on.” Snoop said.

He mentions that him and Dr. Dre have been working on the record every day “trying to go hard” with none other than Stat Quo and the D.O.C. He also said the picture, which is to be seen on twitpic, was in fact Dr. Dre’s idea. While Dr. Dre normally “won’t even let taking pictures of him.” Watch the radio interview here.
