There's been plenty of ink spilled about Beyonce's self-titled album, but one thing that's hard to argue against is that it's her most experimental work to date. The fifth part of her documentary, 'Honesty,' gives some insight on why.

Beyonce, 32, mentions that she's been performing since she was 9 years old. She explains the transition of making music for "the children that grew up" listening to her to adults. "I always feel like it's always been my responsibility to be aware of kids and their parents and all these generations," she says. "I felt like it stifled me. I felt like, in a sense, that I could not express everything."

On 'Beyonce,' she decided to make honesty the "glue" that holds it together. The principle also guides the sexual 'Rocket.' "What I love about this song is it takes you through this journey," the songstress says. "You're talking and you're flirting and you're talking all of this arrogant s---. Then you climax and then you have your cigarette."

The documentary also features visuals from recording sessions, where Timbaland and Justin Timberlake watch from outside the booth. Timberlake was floored: "Um, there's something wrong with you."

Pharrell is also seen giving praise to Beyonce for her creative direction. "Only a mama can talk like that. And only a wife can talk like that," he says. "That's your strength. When does a mother and a wife do that? I mean you just ran through jail and let all the women out. You set women free. I'm trying to tell you that record is a phenomenon."

'Beyonce' has spent three straight weeks at No. 1 since its release last month.
