Does anyone know how I can put music onto a power point presentation?

I have a Mac OS X Version 10.4 using Microsoft office 2004. My 10 year old is putting a project together about sharks and though it would be fun to add the 'JAWS' movie theme. We found JAWS theme on a website but power point couldn't insert the sound (JAWS.wav). Hoping we can insert a sound to play continuously through the presentation. Hope someone can help. Thanks.
