Great, got the original soundtrack today, which means I don't need to rely on my lowsy memory and crappy old monotone keyboard to crack the job. I'm now confident to say I'll do the music -- that is, the formation of the feature length music flow. We still need a technical guru to merge the files of the music fragments with the video clips.

If I can find out which is the best software to use, giving that the adding of music is normally one of the last steps of a movie production, it might still give me enough time to learn the software. Or if we already have someone experienced in this kind of work then that's a quick (and probably better) fix.
