Add background music
I am using 9.09 version of iMovie. I have Mac OS 10.13.6. The song I want is in my iTunes app and I can see it when I press the music icon in my IMovies project. To have the song go to the project the directions say to Add Audio button (it shows an icon of a + in a circle) next to the song. But I do not have that icon. What do you suggest?
