The Hitman: Contracts Original Soundtrack was composed by Jesper Kyd and released in 2004. It is arguably darker in composition when compared to Jesper Kyd's scores of previous or subsequent Hitman games. The score features the same Latin choral arrangements as in all the other scores; however, they are heavily sampled and mixed into the dark electronic soundscape.
As summed up by Kyd, "First of all it is a much darker score. Hitman 2 was an epic story that kind of spanned all over the world. This one, although there are different locations, it's not one big epic story. It's a lot of darker, psychological small stories mixed together, so the score follows the darker aspect of Hitman and his career.
