iPhoto slideshow that uses registered music
I have created a slideshow on iPhoto, I was allowed to utilize the music i have stored in my iTunes library. When i went to export the slide show, I was told that I could export just the photos and the music that isn't registered to an actual artist. My question is:
Is there a way to export the iPhoto slideshow including the registered music?
If so, how?
I imported the slideshow to iMovie instead, but can't seem to insert the music I had from the original slideshow. How do I do that in iMovie?
iMac (21.5-inch Mid 2011), OS X Yosemite (10.10.1)
