The English don't like concepts, really, not from a pop star. It's alright if they come from an 'intellectual,', but from a pop star you're getting ahead of yourself.

For the world to be interesting, you have to be manipulating it all the time.
My kind of composing is more like the work of a gardener. The gardener takes his seeds and scatters them, knowing what he is planting but not quite what will grow where and when - and he won't necessarily be able to reproduce it again afterwards either.
