Witches by Revistronic; What is that music from?

Here is a link to the trailer for Witches, a new title from revistronic:

You might not recognize the background music until about halfway through. This instrumental music is not specific to this game. I have heard it several times before, most recently in some trailer for a sci-fi space film that I can't remember. Does anyone know what this music is originally from?
