I've used a few Brain Sync programs over the last few months, (including Brain Power, Deep Learning & Total Relaxation which I completely recommend) and had hoped Sound Sleep would work for me. Unfortunately, I just could not fall to sleep by listening to this title. The music just repeats itself repetitively throughout the 60 minutes, and for some reason the Delta waves on this program just didn't calm me. I'll have to try another Delta program from Brain Sync.
