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].

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've worked with everyone from Ice Cube to Snoop Dogg ... right across to working with pop stars like Justin Timberlake. Why those artists came to me is because they wanted my sound.

There is a definite Chinese pop sound developing, but I was shocked at how influenced it is by American music.

Madonna has a very unique style and comes up constantly with these great songs.
