Syndicate Wars is the sequal to the class game Syndicate, and comes with some nice audio CD-tracks. There's only three of them (and all have the same atmoshperic, dark feel) so I only included the best one here.

Sadly the game doesn't really hold up to modern standards, with clunky control and getting the speed right in DOSBox is a challenge as well; still, this is an IP that would be nice to see in a new game.
