That's exactly what it is. It's so centered in the middle that it makes it feel hollow. The white noise parts help, but you need to find a way to spread the sound more to give it more fullness.
Nice and simple feel to it. There is something missing in my ears like a missing dimension, but I can't say exactly what it is. Kind of feels a little hollow - not full enough I guess. In any case, the track is well composed and love the way it flows together.
