When I collaborated with Nelly Furtado, the idea for the song structure came from myself, but the lyrics and the ideas behind the songs came from her.

I would give the same advice to anyone, celebrity or not. Produce your own music, keep in original, and be real. You need to earn the respect of your fans for your original work in music, and not rely on your celebrity in other mediums. The same would apply for actors who sing, dance, or even play sports.

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.

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.

Shanghai set out to take over from Hong Kong and I think it's done that. It's got the most amazing futuristic skyline which rivals and even betters Tokyo.

I think anybody that is going to be taken seriously in [music] industry needs to produce their own original music.

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.
