Talk to SFG, he has a capture program that captures the output on the screen. Make your cutscene, play it, and at the same time press "record" in the capture program. Then you get a simple video editing kit (Windows Movie Maker would do just fine), and a song in the format of your choice (mp3 would be best), slap the song onto the audio track in the editing app and export to .avi or other applicable format.
