Download free Nature Sounds

Are you looking for a way to relax?  You can mix your own blend of nature sounds and download it or just listen to it online for free.  My doctor actually recommend that I sit and listen to something similar to this.  When I went in Wednesday, he sat me in a room for about 20 minutes to listen to some from another website.  It did help me to relax a little bit, which helped with my pain management some.  Of course, the one he recommended is not free.  So, I think I will try this one out.
