Hi affricat,
Here's an excerpt from the **Add audio or sound to your presentation** Help file:
PowerPoint can play a song across the number of slides that you specify and then play a new song starting on another slide.
- On the slide that you want the first song to start — slide 1, for example — insert the first audio file.
- Make sure that the audio icon on the slide is selected, and then on the Format Audio tab, under Audio
Options, on the Start pop-up menu, click Play Across Slides.
- With the audio icon still selected, click the Animations tab, and then, under Animation
Options, click the Reorder button.
- In the Custom Animation dialog box, select the song, and then toward the bottom of the Custom Animation dialog box, open the Media
Options panel.
- In the After box, change the number from 999 to the number of slides you want the song to play. For example, if you want the song to start on slide 1 and play through slide 4 and then start a new song on slide 5, you would enter 4 in the box because you want the music to play for 4 slides and then stop.
- Repeat steps 1 through 5 to add other songs. For example, if you add a new song to slide 5, and want it to play across slides 5, 6, and 7 and then stop, you would set the Play Across Slides option, open the Custom Animation dialog box, and under Media Options, change the After box to 3 because you want the music to play for 3 slides.
Hope this answers your question!
