Apply an iTunes song to a slideshow
In the past i have imported the song from iTunes into Garageband, shortened it to where i want and make it fade out rather than having a sudden stop. When i am finished i save it and close GB. When you are applying a song to your slideshow, you need to look under garageband instead of iTunes in the media tab and you will find the song you just created in GB. Add that song to your project and your done!
