I agree with all of the above. My son has Asperger's and used to run from the room with his hands over his ears if I sang a sad or emotional song or if music with too much emotion was on the stereo. Now (at almost 21!) he composes amazingly intricate music on the computer, using Noteworthy Composer and the arrow keys! It's music for video games, and he already has some game writers on the internet interested in him!
