Chris Brown's Graffiti album is in stores today (December 8), and while you may have already heard it — courtesy of MTV's "The Leak" — you may not have heard the stories behind the songs themselves.

Brown has plenty to say on the album, a deeply personal disc that's his first since his February assault on then-girlfriend Rihanna. While the album touches on the incident in a couple of songs — and Brown talked about it at length during this interview, which took place last month — we'll start off with a pair of the album's uptempo club tunes, "Wait" and "What I Do."

"Wait:" "This is a collaboration between me, Trey Songz and Game. Polow Da Don produced it. Me and Polo, we got a lot of different joint ventures. Different rock groups and different groups ... Polo and I have been friends for a minute, so we always be hanging out, and I was like 'Yo man, I gotta get in the studio, let's do some crazy records.' I was always writing with him, like I did the 'Stronger' record he did, with me and Mary J. Blige — me and [Ester] Dean wrote that record. Like, we've always been working in the studio, writing with him, so when it came time to do my album, he already had some joints in mind for me. He had the beats and we just went right to it. Trey Songz wrote his verse, Game did his, but I wrote the chorus and my verse."

"What I Do:" "This is me and Plies. It's kind of a bragging record, though, it's like talking about stuntin' with money and everything. It kind of ties into the movie I got, called 'The Takers,' it's coming out in February. It's a bank-robber movie, that's my character, so what I do: throwin' up my cash, acting like money ain't a thing. The Runners did that joint, DJ Khaled got on the front for me. He blazes it when he get on there. 'We're the best!' "

MTV News will have Chris Brown talking about more songs from Graffiti in another article later today!
