For copyright reasons, we can not include the audio with your download.  You'll need to get your own legal copy of the audio in order to play the sequence.  Most authors have provided the album information so you can get the correct song.  Purchase the correct version of the song via your favorite method, and add the music to your PC.  Once the song is on your computer, open the sequence in the sequence editor, click on "edit,"  then "media file."  Browse to the location of the audio on your computer.  Since identical versions of audio can have different amounts of silence before the track starts, you may find it necessary to use the skew track feature in order to slide all the timing events to match your audio file.
