While this deep bass pitch is perfect for my preference as a sleep sound, the sound loop break, at about every 3 minutes 45 seconds or so, defeats the purpose. If this can be remastered to eliminate the sound break, I'll be back to click like. It's in my history; I will check back on it once in awhile. OH! and, for most people, a sound length of 7-8 hours would fit more with their sleep period. Myself, I usually only get 4-5 hours. Unfortunately....
