Here’s a great clip of Ridley Scott from the Fox Searchlight channel on Youtube. He speaks about the importance of music in editing with various anecdotes about Alien and the inclusion of Baaba Maal in the Blackhawk Down soundtrack.

The right music at the right time can set the perfect tone, and surprising genre choice can add a truly unique perspective to the visuals. As long as the music complements the images and editing rather than overpowering them you can create an emotionally engaging rhythm and tone that couldn’t be achieved otherwise.
