"Delightful" is the first physical single released by Ami Suzuki under the label Avex Trax.
It is commonly known as Suzuki's "comeback single", as it was five years since the release of her previous major work.
"Delightful" was produced by German trance musician Axel Konrad, who gave it a marked eurodance influence.
Since its release, the song has become a crowd favourite, along with "Be Together", at her live performances in music festivals and public events, one of the most remarkable being the yearly Japan nationwide tour organized by Avex, A-Nation.
After twelve weeks in the charts, "Delightful" ended up selling 97,218 copies, and was later placed at number 97 in Oricon's Yearly Top 500 best singles of 2005.
