If you have a Cd burner on your machine, here's a way to make some fairly spooky & original stuff!
First off, find some 'regular' classical style organ music (can find them sometimes at thrift stores). Copy the music onto your hard drive, save the music in wav format to you desktop, then take each song one at a time and decrease the speed by 25% to 75% using your windows sound recorder (standard with windows OS).
If you want, though I don't know the legalities on this, you can take voice recordings and mix them with the music, also slowing them down by about 25% (any more than 25% and it might not sound right).
Slowing the music down will make it sound way creepy... you can also add an echo effect with sound recorder, too. But don't overdo that or it'll just be annoying.
Trust me, this makes an incredible effect! I've used this method with flash loops and voice recordings to create some killer music and effects.
Once you've created your music and sounds you'll have to convert the wav files back to mp3 to play on your machine---as long as your player handles mp3 you're fiine.
Good luck!
