My first experience with binaural beats was with a therapist I was seeing through the veteran's administration. This was about 20 years ago. I found the binaural beats very helpful with stabilizing my moods and for relaxation. I do use the youtube ones now and then. Very helpful for restful sleep.

Binauaral and other beats are also said to "cleanse" the pineal gland (third eye). I'm inclined to believe it, because I feel better after listening to the beats.
