I've heard a lot of talk of binaural beats since getting into lucid dreaming, both of which I found out about on the Dreamviews website. What I learned from there was similar to what this article states, except it comes from people who get themselves educated on the subject and discuss it, or they're just asking about binaural beats. Either way, this article sounds rather absurd to me. Music has been a gateway to drugs for decades, it's just a matter of how you look at it. Saying that listening to it makes you want to get high introduces nothing new, and is, like mentioned before, just some scare tactic to achieve some goal. Shame on them.
