Oh, this is lovely. Both with and without bangs are very, very good in their own ways. I particulary like the bits that begins at around 1:10 and 2:00, and 2:30, and 3:14, and... yeah. It just keeps getting better, and better, and better, and better, the further you get into the track.
Warning: I'm about to step on your artistic integrity and make a lot of critical remarks which I really have no background to make, but I will anyway. I don't produce anything related to music myself, so if you want to ignore this, feel free

Here goes:
I'm almost sure it could be split into several looped segments, which could be good because it seems a bit wrong to put [a song that doesn't get really distinct until after +1 minute] into the game on screens which the player will likely not want to spend too much time in. Much like the main theme for Civ 4, in which you hardly ever get to hear the "crescendo" unless you sit at the main menu for quite some time.
What I'd suggest would be:
- to use the first 1:30 of the track as a basis for a loop to play on the galaxy map, and in other places where you don't want to agitate the player too much.
- to use the time from 1:30 up till 2:30-3:00 or so, as a basis for a second loop with the same purpose as the first
- to use the time from 3:00 and out as a basis for a loop for the combat screen and other such activities.
- to retain the original track as it is right now, and use as a "main theme" for the credits, opening screen, main menu and so on.
Doing this would also create a feeling of unity and thoroughness in audio design throughout the game, in that quite a lot of music is added which bears the same style, sound and feel.
