I copied every music of Deus Ex from its "Music" folder. However, I couldn't find the music can be heard on the streets of Paris, even though I can hear that ingame.
Which UMX file contains that? I could notice while playing them with VLC media player that these files contain certain chillout music, battle music, end music and dialogue music the same file.
(for making the question clearer, this is the music I'm talking about - thanks for Brant for warning)
