In a video
about the making of "Habits," Plested explained how a circular saw was integral to the song's sound. He was working on the tune on the stairs outside the studio when he heard a noise he couldn't pinpoint. "As I was playing it, there was this weird sound in the air, and I thought it was just like atmosphere - it was in my head or something, I didn't know what it was. But then I stopped playing it was like [mimics high-pitched whine] sound going on. So I was like, I need to find out what that was. It turns out that these studios were being built and one guy had a circular saw going, and the circular saw for some unknown reason was in the key of E, somehow, so it worked perfectly. We've actually got it in the track. I think that's what makes it sound so dark and eerie and tense."
