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 wish my friends at William Morris Endeavor all the best.

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.

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.

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.

Let their music skill speak for [itself]. If they are producing good tracks and are resonating with their fans, or even gaining new fans, then that's great.
