I agree with both reviews prior to mine. 432Hz is why I purchased it. I too a nap listening and it really worked. I a kind of purple symbol and it startled me at first. All in all the music does work. I use it to help me sleep at night (via echo device). I created an album using only the 432Hz.

I bought this for the 528 hz healing tones. It's supposed to repair mutated genes. Is it healing me? I don't know. I've been listening to it as I fall asleep until my earbuds bother me. I do fall asleep more easily and seem to have a more restful sleep.

I listened to this albumn twenty times this week at my work as a massage therapist. I deleted about 6 songs off the playlist, but overall the sounds did not get on my nerves. The music does not have much melody, and it is not very "spacey." I found it peaceful. The songs I deleted had a twangy piano sound. After I deleted the songs that annoyed me, I still had over an hour music. Clients were neutral about these sounds, neither liking or disliking. I use Liquid Mind also during sessions sometimes when I need neutral/drone music like this.
