Can't use modified music in Photos for slideshow??
I'm new to Mac. I modified some songs for use in a Photos slideshow. Basically, I just shortened them. I placed them in my iTunes folder, but they don't show up in the iTunes dropdown under Music Library in the Photos app. I read that you can only use iTunes downloaded music? So I'm stuck using full songs? That sounds incredibly limiting. If true...bummer and I need to go to a different app. If not true, please show me the magical steps to getting my own modified songs into that dropdown.
