George Skarbek’s column in The Age this week answers this question:

Q: How can I set up a music file to play through an entire PowerPoint presentation? I can get it into one slide, but it stops when the slide changes. P. Turnham

My suggested answer: You shouldn’t. Are you trying to fecking torture your audience or what? Just because you found some tinny bit of computer music that would have the original composer turning in their grave doesn’t mean anybody else wants to hear it, let alone for the duration of a complete presentation. It’s crap, dude, pure crap.

Show your slides, know your facts, talk to your audience, take questions at the end, and don’t over-do the cutesy clipart or animations. That’s how to do it.
