"Cloud Nine" was inspired by a break-up which is present in the lines "If you want to live, let live/ If you want to go, let go/ What are we doing here?/ Because I can live without you." It uses strings, studio effects and Lee's "layered moaning."
"If it’s something like the song "Cloud Nine," we got a cool drum beat that we liked. Then she came up with a vocal melody. It was cool because I just took the bass and started writing the bass line to the actual vocal melody. That was something different that I had never really done. We never really had any set way. If there was an idea, we would just do whatever we could to move forward with it."
