This goes with the theme that Jason Weiser explored in his "Hawkins, IN in Twilight 2000" thread - an alternate history of a Cold War future rooted in the 80's, or, more correctly at this point in time, 80's nostalgia.
For me, this cover song perfectly captures my current self looking back on my 1986 self imagining a small military unit in a future World War III. (Yes, "Tour of Duty" was must see TV for my middle school buddies and I!)

I use music in my games and this will be my new theme song!
