Thanks for the info. While I was waiting I did a little poking around and found another way. I highlighted the first slide went to Slide Show>Slide Transitions and set the sound to the wav file I wanted and then chose apply, NOT "apply to all" then I chose the slide where I wanted the music to change (Slide 6) and repeated the proceedure. When I went into the slide show it did exactly what I needed, It played the first song contiuously until slide 6 and then change to the new song without a hitch. Just wanted to pass that on. Thanks again for your help. I going to check out your method to see how it differers and the advantages.
