The Hitman: Blood Money Original Soundtrack, composed by Jesper Kyd, was released on May 20, 2006 by Sumthing Else and Eidos Interactive|Eidos. The score was performed jointly with the Budapest Symphony Orchestra and the Hungarian Radio Choir. It features Kyd's trademark ambient and dark, foreboding arrangements with the choral parts in deep brooding Latin..
In the composer's own words: "It seemed like a natural choice to mix things up for the Hitman: Blood Money score. After the electronic-driven score for Hitman: Codename 47, the orchestral Hitman 2: Silent Assassin score was a new direction for the sound of Hitman, although there are still a few purely electronic tracks in Hitman 2: Silent Assassin. For the third title, Hitman: Contracts, we wanted to go back to the games's roots and create an updated and more modern electronic score. So the Hitman series has a strong background in electronic music."
