Can't sleep without it
I purchased this CD 3 or 4 years ago and now put it on endless repeat every night before bed.*No thunder or tropical bird calls; no sudden noises (or silences) of any kind. Easy to drift off to sleep or to meditate without distraction. Heavenly!*It is a bit soft -- I have to turn the CD player up fairly loud to make sure the rain sounds are at an appropriate level, similar to listening to rain outside my bedroom window. If you plan on playing this on a player with weak speakers or to cover a lot of heavy noise, you'll need extra amplification somehow.*One reviewer complained that there is not a lot of variation. True. It's a just steady rain, not a weather drama. If you're looking for an imagination aid you probably should get one of the many, many rain recordings that include thunder. But if you're looking for a soothing natural soundscape to provide white noise I've never heard anything better!
