To promote the international formats of "Kingdom Hearts", Utada re-recorded an English language version entitled "Simple & Clean". Both the original edit and remix version by PlanitB served as international theme songs. It did not appear on Utada's English studio album "Exodus" (2004), but the original version was included on her 2009 English studio album "This Is the One". It was later released as an A-side 12-inch single with Utada's single "Colors" in 2003, and received positive reviews from most music critics.
