Why do I only feel calm with nature-sound meditations?

Guided talks frustrate me, but meditations with only rainforest or ocean sounds work instantly. My energy suggests an airy, anxious, and fast-moving mental energy. Do these nature sounds provide the grounding earth element my airy, anxious mind karmically lacks? This immediate calm suggests the sounds are providing a balance my body desperately needs for focus.
