Browsing through Gizmodo and came across an article entitled "Help! Teens Are Using Digital Drugs to Get High"; short summary: listening to sounds via headphones which induce a translike euphonic state of mind, presumably like getting high. The article provides a link via a Youtube video in which you can try for youself.
I guess what's more interesting is how serious people (a.k.a. politicians) are taking this. I'm currently without a headphone amp and without any adapters to connect my headphones to test it out; via speakers, it does sound annoying.
Oh wells, back to the other usual suspects.
