i guess the vid will be short, the music should reflect it in it's dynamic too,
no matter what you choose a classical tune or a rave.
if i remember your plot right, a silent start, then suddenly something that makes you feel you would have to stand up or take distance.
personnally, but i only speak for me, i would choose a classical tune, but of course not blue danube, you don't wan't to send us to sleep, won't you?
something other i like is this, it's got far to less dynamic for the plot, but could be a good start
spacewarzopus you would have to open it with winamp or some else player, capeable playing back a protracker mod.
personnally i use it as title track for FFED3D and the length is fixed up by me to make it fit for, if you like to convert it to mp3 and use it for your FFED3D you would have to number the tracks in folder "space" to make shure it is track 18.
then it will be loadet allways as first track when FFED3D starts.
