Do you want to add a sound track to your PowerPoint presentation so that it plays across slides — so that when you move from one slide to another, the music continues playing without any interruption? A soothing background music score playing across your presentation slides can be a good move, as far is its not distracting your audience. Of course, if a live speaker is spearheading the presentation — then it goes without question that you don’t want to add a sound that spans across slides.
