My grandmother always used to wear this English perfume called Tuberose and then she died and then I dated this girl who wore the same thing. Every time I hung out with her, I could only think of my recently deceased grandmother. So sometimes a signature scent can be good and sometimes it can be bad.

I think, you know, for me, whatever I need to slot into to make that music the best it can be or help the artists, or whoever I'm working with, achieve whatever vision they have in their head for a song.

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.

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?

I don't have a crazy rider clause saying I have to stay at fancy hotels. I don't have a problem with staying at a Marriott. But I will admit that I've gotten just basic, regular service there.

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.

I didn't start making music in order to be famous.
