Quite darker than the rest, if I do say so myself. If this doesn't work, then I'm stumped.
If you're not on a work PC, may I recommend VLC? Small, lean no-nonsense interface, can be used as portable app on a pendrive and plays... about every format?
Some alternate suggestions
Loving the mod. Does Lal currently have diplo music in the latest build? If he does it's far too quiet.
I have to think of the Caretakers when hearing it - the sad theme fits them a bit, but it's not a perfect fit, I think.(Sounds vaguely sailor-like, although it may be somewhat sad and not aggressive enough.)
