Final cut express how to overlay audio?

Now that you've finished your movie in Final Cut Pro you are ready to add a musical score to it. Adding the perfect music can help achieve a desired mood that may not be attainable through editing alone. The audio track can also help mend editing cuts together seamlessly. What we will examine in this tutorial will be adding a new audio track and creating a fade out. Final Cut Pro accepts many different audio file types, including AIFF, cdda, Sound, Wave, and MP3. These file types each have different levels of quality. When you are ready to import your audio file you will need to go to File>Import>Files Then browse to the file that you would like to use in your video. To avoid copyright issues I am using a royalty free music file titled "Hometown Hero."
