Amazingly good and free!!!

There are only 5 choices of ambient sounds/music. Most have music but you can lower the sound of the music if you like, I personally prefer the music. I actually like that it doesnt have too many choices which could overwhelm you. But maybe 2 or 3 more would be fine. Overall great and free!
