I had a somewhat frenetic childhood because my mum and dad split up when I was five, and then my mum remarried.

You know, it's weird. It's - it hasn't really changed my life in any kind of way that I can measure. I mean, it's obviously such an insanely amazing thing. You know, none of my other records I've ever had before even broke into the top 100.

So sometimes if I'm working with a rapper, like Ghostface Killah or Nas, producing usually means, in hip-hop, that you make the music. You make the beat, and you give it to them. And they write the rhymes.

My mother was pretty strict. I hated it, but maybe it made me a bit more sensible.

You just pick up a little bit of whatever the ones you think are appropriate, and you try and, you know, combine them. And then you bring in other people that are great for the things that you're not so good at.

So when I was working with Amy Winehouse on "Back To Black," you know, she had all these beautiful songs, incredibly well-written and just her on an acoustic, nylon-string guitar. And she'd play them for me, and then I would kind of drum up my idea of what I thought - make a demo with what I thought the drums should be doing, the guitars - like, quite a crude demo.

And then, also, when you're doing something that doesn't sound like anything else on the radio at the time, you almost need to, like, ironclad it to make sure it gets through, you know?
