I would really like to see a software that claims to be able to remove music from a sound file. That is pretty much impossible unless they are separate tracks. The frequency response of both sound effects (voice over included) and music spans such a wide range in the audio spectrum that you can't just EQ it out without getting heavy losses in the quality of the sound effects.
I think your best bet is to get your hands on a professional sound effects library if you want something that sounds even half decent, or borrow a shotgun mic and recorder from somewhere / someone and record your own.
Oh, forgot about this post. The video was done a few days after posting it anyway. Here it is https://www.youtube.com/watch?v=NXNUJM01NVY
There is such software, but of course it won't make the sound perfect and clean. The result depends on what music/file... is having the music removed from. YouTube used it here to remove music, left some sound at least, by far from perfect: https://youtu.be/5ZBvtdYdVkM?t=11m47s. Normally it sounds like this https://youtu.be/5ZBvtdYdVkM?t=23m42s.
