To make to lights sequence with the music: double click your sound icon on the task bar. a window should pop up. click options, then click properties. click recording. then enable your computer sound input (usualy called what you hear). then click ok. then exit. UNPLUG ALL MICROPHONES! Works best when downloaded. oh yeah, and about the space mountain music. MY FAVORITE RIDE IN THE WORLD! I HAD TO PUT SPACE MOUNTAIN BECAUSE IT IZ AWESOMENESS! if it doesnt work turn you computers sound up.
