After I felt I had enough pairings to constitute a video, I obtained a copy of The Empire Strikes Back and imported it into iMovie. I cut out the scenes I wanted one by one, importing each song from iTunes as well. Sure enough, my knowledge of the movie and my iTunes library allowed me to do this efficiently. Along the way, I trimmed the scenes and music to match what I wanted, also taking time to adjust the volume levels of both the songs and the movie audio.
