Well recently I have been listening to nature sounds when I goto sleep. I have netscape radio. In the netscape browser. You can click on the nature sounds and it will play real scenes in nature. Like at the beach or rainforest and you can ear every little bird every chirp from crickets and insects just as if you was standing right in the forest. They make em run for like over an hour and sometimes longer or shorter. I have a hard time concetrating. but I think someone who is good, could use this. I tried to imagine myself in the scene of nature they have playing and with its true realism it would be an easy task. Has anyone else use this?
