I'm obsessed with the science of music. I'm obsessed with the way you can string notes together and they can do something, and you play the same notes in another way and they do nothing. How the essence within songs - within words, within lyrics - finds its place.

I kept saying I got sick of listening to people's productions, like people who had no ideas, no songs, nothing to say but could still con people's ears into thinking those songs were there by the application of production. I kind of wanted my record a little more honest than that: "Well, this is us. We put a microphone on it. Here it is."

In an odd way I thought I was lowering the bar for myself, in saying, well, I'll make a pop album. But in a way it's kind of harder to make pop music. It's like the more abstract you get with music, you get into that emperor's new clothes thing, where you can go anywhere, and just claim that your audience may not be prepared to go with you. But with pop music, I think everybody understands the form, everybody knows what it's meant to do. So I would say it's harder to write that kind of music.

I don't make records for this medium with which we're going to sell it. The selling of it can never be more important than what you're actually making. There's too much of that in the world - in everybody's world, not just in music. There's too much, "Are you hip to this kind of stuff?" "Hey, this is cool." "Are you hip to it, because this is what we're selling today?" I think it's bullshit.

There's always this talk of the industry of music and about selling records and whatever, but that ignores probably the majority of music that isn't about trying to sell itself, that isn't about being connected to any industry. There's a huge amount of music where someone just happened to have a tape recorder and turned it on or hit the red button while they were in the back of church or recording something in their front room.

I've said the line about Ray Charles a million times, but nobody listens to him singing "I Can't Stop Loving You" and wonders who Ray can't stop loving. They apply that to their own lives. That will happen with my songs.
