Editing is now the easiest thing on earth to do, and all the things that evolved out of word processing - 'Oh, let's put that sentence there, let's get rid of this' - have become commonplace in films and music too.

The lyrics are constructed as empirically as the music. I don't set out to say anything very important.

Lyrics are always misleading because they make people think that that's what the music is about.

So I believe in singing to such an extent that if I were asked to redesign the British educational system, I would start by insisting that group singing become a central part of the daily routine. I believe it builds character and, more than anything else, encourages a taste for co-operation with others. This seems to be about the most important thing a school could do for you.

I always have wanted to know how the whole thing was done, what the process involved. And I don't particularly enjoy that my music is stripped of ancillary details, and it just sort of comes out of this big tap called the Internet like water. I like some of my water to be neatly presented in a bottle. With a label on it.

In fact, quite a lot of what I do has to do with sound texture, and, you can't notate that. You can't notate the sound of "St. Elmo's Fire." There's no way of writing that down. That's because musical notation arose at a time when sound textures were limited. If you said violins and woodwind that defined the sound texture; if I say synthesizer and guitar it means nothing - you're talking about 28,000 variables.

The tools are evolving, and people's interests are evolving as well. So, suddenly people like to hear bands, people like Devendra Banhart or the xx, bands that make a kind of virtue of sloppiness. That isn't what they would describe what they're doing, but the fact is they make a virtue of the sort of hand-made nature of what they're doing.
