Information
This single was used in Japanese commercials to promote the Nissan Cube. The commercial made its first television airing on March 1, 2007. The single was sold for ¥555 or roughly $4.50, an unusually low price for a physical single, although this price may be attributed to the single containing only 2 tracks as most singles contain 4. In its first week, the single placed 2nd on the Oricon weekly singles listing.
