I was half tempted to try to explain some of the details about how this is done using evolutionary music, but I'll not bore you unless you want to dig deeper. If that's the case, read up on their Wikipedia page.
What is interesting is that they've developed algorithms for various purposes, such as the perfect, non-human songs for jogging. They've also been subject to therapeutic clinical trials that concluded that specific styles of songs can perform feats such as reducing someone's fear of heights, their stress levels, and even their perception of pain.
Shit's cray. I've seen the Matrix. I know where this is leading, and I refuse to be a living battery! *Throws my computer out the window*
