The information in this presentation is excellent, visual display superb, voice of the presenter is clear and distinct, music is distracting . . . very distracting, especially the intermittent stereo (one ear only) jingle. Could the music be removed? I may come back to view this video again when I have more tolerance. It's too bad because the rest is so good.
