Subliminal audio for self improvement

I was just wondering if anyone here has tried it. I just came across 2 major brands on the internet and it seems like its got a lot of potential.

I’m going to list them later, but my second question is, once people start pirating them what’s to stop them from changing the actual subliminal message around and put in a “virus or worm” and create an army of “human-nets” (for those who didn’t get that that’s derived from bot-nets :stuck_out_tongue: ).

Here’s Brain Sync where they play with brain waves. Here’s what they have to say:
“Brain Wave Therapy can easily guide you directly into beneficial states of consciousness where both hemispheres are balanced and brain activity is organized and coherent. Our harmonically layered frequencies drive brain activity into a wide variety of states such as Gamma for heightened awareness and precognition, Beta for concentration, Alpha for creativity and relaxation, Theta for learning, memory and meditation, and Delta for sleep and healing.”

Then there is Glen Harrold who “as an experienced clinical hypnotherapist has helped thousands of clients through a wide range of problems, such as anxiety, fears, self-esteem issues, weight control and many stress related illnesses. He has combined his hypnotherapy skills with an extensive recording knowledge to produce a uniquely effective series of high quality hypnosis recordings.”

Any opinions?
