I downloaded all the IOA music from Napster a year ago and the entry song was not found.
My favorite is the one with the bells ringing and the birds chirping.
The music from the different lands is whacky cartoon, or orchestra music that sounds like it's in a movie. Good in the park, but not something you would listen too by itself.
Now, the Mythos CD is a different story. The 2nd album, The Reality of a Dreamer by Mythos, is awesome. I listen to that one all the time.
