I believe in Binaural audio effects. They are real and can influence many things. Even when I listened to the first song my ears picked it up before you told me. I know it works best with headphones though. I have a few apps on my phone with this stuff. Stimulation for your brain. Can help you focus more, make you fall asleep, and even do the opposite as in keep you more awake, even supposedly help you quit smoking etc. It's real stuff though. Just as audio can manipulate someone, they same can be said for visual stimulation as well. I think companies, products, etc. know this and can work it in their marking. Now I am getting off track.
