There have been studies on the effects of classical music. The effect was found to be temporary. I am no classical music expert;but certain passages of Mozart make me feel joyous. Some of Bachs pieces imbue me with a strong feeling of calmess. These feelings don't last but they are very pleasurable.
After several years of listening to Holosync I have changed. I am far less reactive. I am more self aware. I recently had a six week break from listening to Holosync and there was no fall off in these results. Holosync is in a different league to other soundtracks.
Notwithstanding this I do feel that Holosync is way overpriced. Also be prepared for the long haul. Incidentally learn the Sedona Method (the book is cheap) it really helps when dealing with overwhelm.
