"I literally have seven albums done," T-Pain tells the BoomBox. Yet the 'I'm Sprung' singer is running into some issues narrowing down the final tracklist for his fourth studio album, 'rEVOLVEr.' Singles from the album started popping up last summer, suggesting that the effort would be out by the end of 2010, but now T-Pain reveals he's shooting for a "very end of September" 2011 release.

"By the time I choose when I want to release it, I've recorded so much more that it's like I got to replace this song with this song because this song is not as good as that," T-Pain says of the mind game he is facing dropping 'rEVOLVEr.' "I'll go through something; something can sneak on or I meet a new artist that I can do another song with. I'm just taking stuff off and putting new stuff on."

T-Pain has never been a stranger to the guest feature. Two of his many assists have earned him Grammys -- in 2010, for verses on Jamie Foxx's 'Blame It' and in 2008, on Kanye West's 'Good Life.' And the former Auto-Tune king's not shy in trying to return the favor on 'rEVOLVer.' Chris Brown and Rick Ross are featured on the previously released 'rEVOLVEr' singles 'Best Love Song' and 'Rap Song,' and T-Pain isn't stopping there.

"5 O'Clock' will be the next album single," he hopes for 'rEVOLVEr.' The song features a sample of Lily Allen's 'Who'd Have Known,' and Pain hopes to jump in the studio with the British pop singer. "It's an 'I miss you' song," he explains, before beginning a mock conversation, "because it's five o'clock in the morning and 'Where you at? Come home. OK, baby, I'm coming home.'"

T-Pain doesn't elaborate on who he's missing these days and the BoomBox was told not to ask about his recent Las Vegas romp with Kesha. But when asked about the recurring love theme on 'rEVOLVEr' -- the question prompted by song titles like 'Best Love Song,' 'Reverse Cowgirl' and 'Take Your Shirt Off' -- T-Pain explained with a laugh: "I just have sex all the time, so that's what is on my mind when I'm writing, so it's kinda hard not to write about sex."

And then, in true T-Pain fashion, he says the biggest party anthem on 'rEVOLVEr' is a track he's titled 'Give It to Me.' "It sounds more sexual than anything we've talked about today, but actually it's not," he promises. "I think Pitbull is gonna get on it with me, whenever he got time."

Pain did a little spring cleaning with his 'rEVOLVEr' tracks, releasing the Whopper of a mixtape 'prEVOLVEr' just last month. "The crazy thing is 'prEVOLVEr' is made up of songs I know I'm not gonna use on my album. That's how many songs I have recorded," he justifies. "I can just pick 30 of them and be like 'here, have those' and I've still got enough to work with."

While the delays of 'rEVOLVEr' can be blamed on a poor music climate and the sheer volume of songs, talking to T-Pain it becomes pretty apparent that the biggest factor in the delay of releasing 'rEVOLVEr' is T-Pain himself.

"I'm just really going in hard on myself, and everyone that's around me," he says. "I've always produced 100 percent of all my albums, so now using other people's production -- like Yung Fyre -- it's taken me time to adjust. I'm still not letting anyone write for me, so that's even more of a challenge -- writing to other's people's music. It's a lot going on that's keeping the album back, but this is gonna happen real soon. I think I'm in a good place right now. I was real depressed when I toured all the time. The songs weren't coming out good; everything was about killing myself, a lot of songs that should probably not be heard. Now, I'm happy with what I'm doing. I'm in a real good spot."

And finally, T-Pain gives one last reason.

"To me, the more reason why I haven't released it yet," he says, "is because I just don't think it's good enough yet. And, how long it's been since a T-Pain album has happened, the longer it gets in between then, the better my album has to be."
