This is complicated, not that it is a bad thing at all. I have listened to it 3 times now. In my case I think of movement of rotary blades, like a helicopter, or even a boat moving over water at a great pace, like a jetboat in a river. The "screeching" adds a uniqueness to the journey. I like it 🙂 I too would be interested in what images are generated in minds when others hear this.
