This might be a controversial thing to suggest, but in a quest to understand and relate to terrorism or school shootings, sometimes it feels like it's real, the appeal. As we've seen with ISIS, it's not always the devout who are getting into it; it's just people looking for a sense of belonging. The more they feel they're up against, the more intensity the cause has. It's an epic clash of cultures, and both sides are playing that up, but it's human beings disaffected, detached, and lonely.

I think any songwriter or record, no matter how good it is, can become tedious if it's the same person's point of view. After four tracks, you start to get worn down no matter how good it is. It can be relentlessly good, but it's still going to wear you out.

I don't get particularly precious about things like this, though. Like the record company said, "We need a radio edit that delivers the hook" - I don't even know what they consider the hook in that song ["Oh No"] - "that delivers the hook sooner." So I'm like, "Okay. I see that." And they were all walking on eggshells, like is this going to be sacrilegious to me or something, to mess with this art I've created? And I'm like, "Great. I get to tinker with it, I get to mess with my song some more."

Songwriters can sort of get away with murder. You can throw out crazy theories and not have to back it up with data or graphs or research.

I didn't have the patience for the research, or anything like that. I just like how it sets the imagination off. It's just an area that's very fertile for great words. Great metaphors, potentially.

I've always had levity in my songs, so I like to turn things over, twist them around, and make fun of myself.

I've literally opened it up to suggestions and it's totally chaotic and kind of a bad idea. You don't need the actual feedback to get a sense. When you're showing a song for the first time, people can feel that newness.
