I never thought electronic music would get as popular in America as it has. When I first came to Vegas in 2009 for my residency - we were they only people playing electronic music at that time.

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.

U2 and folks like that. They all have that similar drive and that belief in themselves. They're early birds ... they're up working when everyone else is sleeping. They're simply all great at what they do.

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.

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.

It's good to see that America has a hub for electronic music in Vegas, like Europe has with Ibiza.

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.
