Lightning Bug is a great app for my phone that I found on the Android Market website. It is basically a white noise player that allows you to customize whatever type of sounds that soothe you. A couple of great features are the ability to use the sounds to both drift off to sleep (on a timer) or wake up to sounds. I really love it, and often use it at work to drown out the office sounds that can be so distracting or annoying. Also, it's a free app - I recommed it to all who can use some soothing every now and then. And I guess that would be everyone!
