All of the artists that I've worked with have an incredible work ethic. And Madonna has the best work ethic of them all. I've learned a lot from being around her.

When I was in the studio with Madonna, we would work 12-hour days. If you want to work with the best, then that's what you have to do.

I had Ice Cube on my first album, "Bunker," and then I did a remix for Snoop Dogg. I've worked with Grandmaster Flash and Pharrell. It's a different work process and there's a different take with how you produce [hip-hop].

I'm about to start working with a singer I met on my last trip: she'll get international exposure, and I'll have a song out in that market sung in Cantonese.
