TSUKINOSORA is involved in many forms of music creation,including TV and radio themes and background music, and video game and film scoring. One of her better-known songs, "Luv Letter", which she wrote, and on which she played piano,for DJ OKAWARI, was used as the exhibition program music for the 2009-10 Olympic season by Daisuke Takahashi,whose sterling accomplishments in the world of figure skating have made him immensely popular even after his retirement from competition. The song's delicate yet refined, made-in-Japan sound became an instant worldwide sensation.
