The soundtrack of TNM was composed by Graeme Arthur, Leonardo Badinella, Steve Foxon, Brian Giannotti, Jonathan Gladwill, Andrew Livingston, Martin Ahm Nielsen and Trent Robertson. As each artist comes from a different background, the soundtrack contains various mixed genres, including ambient music, jazz fusion, techno, light rock, metal and classical music. Similar to Deus Ex, each setting in the game has multiple tracks, with the actions of the player affecting which track will play at any given time. For example, joining WorldCorp will change the track played in the rival PlanetDeusEx building from Democracy, Pt. I to Democracy, Pt. II, a more suspenseful track containing similar motifs.
