The music had to be rooted, and yet had to branch out,like the wild imagination of a child.

I played a couple of ideas and then had this unusual texture underneath which was like this little granulated kind of pipe organ almost like a scratchy record which he started [inaudible] brilliantly. "Oh I love that song." And when things go fine, it's good. So he started loving that song and that song was used quite a lot in the movie which is very granulated stuff on the guitar.

Since I worked with Danny Boyle before on Slumdog Millionaire, we have great success and everything. So, when I first got the script and the screenplay of Simon (Beaufoy) and I was reading it, even before the shoot, some kind of sounds came into my mind and I put some stuff [down] and sent it to Danny when he was cutting the movie.

I listen to everything. As I told you, sometimes I just want to shut off from music and be silent. Then I play a song and it's refreshing. It's almost like initializing yourself. Recently I was in South Africa doing a press day for my tour. I listened to this band called "Freshly Ground." They were doing a live gig there so that's the last thing I've heard.

That was a very different emotion and I felt Dido's words would be good and I had a template with my voice in it. Then, when he heard it, he wanted both our voices together in it and that's the scene when he sees the boy and then he gets charged to go on that final cutting effort.

I think I would like to discover a new root where people don't get bored with people singing boring lines but something exciting. That'd be interesting.

I like music that is able to stir my soul. My music is a spiritual exercise
