I discovered that you can add music through PowerPoint (Insert >> Audio), but I have a few questions about that. I had some narration on my slide, and I wanted to add background music. But when I added music using PPT, it overroad my narration. I haven't played around enough with it yet to discover if I just need to increase the volume on my narration, or if the narration is completely gone once I added music. The other thing I noticed is the the music is really loud - even when set to PPT's lowest volume setting.
I know having both narration and music is possible with Snap! because on the Snap! Channel there are examples of it.
