Obviously, it's gonna be the "Trepak Russian Dance."
...though I kinda wish that was the truth, there's
waaaay too many good tunes to name. What makes it worse is that the original music they keep appending is in the same caliber of quality!
Definitely agree on "Abandon All" being very iconic. Before event updates, two of my favorites were "Containment Breach" & "Pathogen" for just doing an amazing job of getting me pumped.
Event exclusive tracks that really get me going would be "Full Burn" & "Launch Sequence" (the latter making me nostalgic for the "Original Sin" level in House of the Dead 2).
However, "Dread Conductor" takes the crown of making me feel like a total badass.
As for the Trader breaks, "Surface Tension" is my hands down favorite. Though I have to give serious accolades for "Drifting Through The Bodies" for being a redneck reprise of "Wading Through The Bodies" (that was bloody brilliant).
And then...there's "Hush, Little Ones (midnight comes)" which made my jaw hit the floor the first time I heard it. I don't know if it was the ocean waves or the orchestral strings, but that song made me feel like I was somehow already vested in an epic journey... D:
I hope it gets revisited down the line...
