I had the same thought myself yesterday! What I tryed was just sliding a CD into the drive. It works great!

. First I pushed on the little Microsoft flag button. It paused the flight and I was sent back to desktop. Then I just slid in the CD and my music match program or any other I would think started playing. Then minimize what ever player you have and click on the flight simulator button on the toolbar below. Unpause the flight, Press "Q" and crank up the sounds. I went to Virtual Cockpit mode, listened to Led Zepplin and watched the clouds go by. ( On Auto Pilot :o) PS. I just cant figure out how to get those radios to work!
