When the sound file is added to the first slide, by default the slide
will not advance until the sound "animation" is complete, that is PP
wants the song to finish before advancing to the next slide.

You need to set the Custom Animation options for the time of the song,
I do not have the Mac version so I cannot tell you specifically where
to go, but you need to click on the speaker icon on the first slide,
and then select Custom Animation, you should find Effect Options and
select this. There will be a place to specify when to stop palying; one
of the options is to specify the number of frames. Simply enter the last
slide number in your presentation. That should fix your problem.
