How do you make a song play continuously throughout the presentation on Microsoft Powerpoint 2003?

Answer 1

Insert the song into the slide, then right click the icon for the sound and select "edit sound object." There's a checkbox marked "Loop until stopped". That box should be checked if you want continuous play.

Answer 2

If your commands aren't working, then copy the music file, change the name and run them both back to back.
Powerpoint can be buggy.
I really hope your not going from pc to mac or vice versa.
