Rocket Sneaker is a piano-driven tune, reminiscent of rag-time music. It describes saying "thank you" to the Earth before going off it, but remembering that one is always "chikyuukko (地球っ子 (Earth child?))". One × Time is a more mature love song, describing feelings of true love. It is lyrically confusing, but Ai revealed that it is from the viewpoint of a clock. Sora to Kujira is more of rock/pop song describing a whale that returns to the sky to join its mama (papa in the second chorus).
