All thouse sound things with water or creek or river or whatever. They all sound to similar to someone taking a piss to put me to sleep. -_-; And the ones with birds only aggravate me and wish I had a gun to shoot them with.

Enya is good to sleep to and I've fallen asleep to Pink Floyd quite a few times. Good stuff. I like listening to the theme song from Braveheart. That always makes me feel calm and tired.
