Requiem for a Tower is a good and the de facto usual example/symptom of this problem.
Not that I don't understand that it's difficult to find fitting music that is also good, and hasn't been whored out by everyone else.
When you make your thing, you want it to be grand and epic and you go in with the best intentions at heart, as you liked the popular music piece, but the problem is so did everyone else and they beat you to the punch so many times, that the (experienced) general consciousness is reeling from the shock.
Anyway, this shouldn't really diminish all that much from the video.
I thought pretty much everything else in the video was fantastic. The vision for creating it and the editing in particular (camera shots) stand out. We've seen this stuff time and time before, but when we see it, it's usually in the bigger budget films where people get paid well to do it, and while it may be an overused effect to dramatize large scale space violence, it doesn't change the fact that it fits more or less perfectly with Freespace (as a distillation of the general experience).
It's very nice. I enjoyed it. Especially the thematic throwback to the FS1 intro, but changed so that it's got an ebb and flow of futile resistance from the Terran side, essentially being a chronicle for the entire Freespace series.
Funnily enough, Vasudans aren't present, which is somewhat of a humorous state of affairs, on several levels, for several reasons.
