1.	"Roketto Sunīkā (ロケット スニーカー; Rocket Sneaker)" (Music video)

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).

Music video

The Rocket Sneaker PV features Ai in stop-motion frames as the camera goes around a path of frozen figures of her doing everyday things. During the chorus, many of her begin to sing in unison. At the end of it, the very last Ai starts to move around, revealing that the path is a loop, and then she starts to go around the path, as the other Ai's have vanished.

Despite its status as an A-side song, One × Time doesn't have a video.
