Go to www.timstvshowcase.com under Series. Go to American Dreams, and download the theme song. It is completely different from what they actually use.

I believe that is the themesong to American Dreamer. WaveThemes.org (http://www.wavethemes.org/themt-a2.htm) has the following:

AMERDREM.ZIP 150244 03Jan98 | American Dreamer (NBC 9/90-6/91)

A file entitled amerdrem.wav is available for download at Sound America (http://soundamerica.com/sounds/themes/Television/A-B/) (and there are no files for American Dreams, which is much newer). As far as I can tell it is the exact same file at Tim's TV Showcase.
