I personally have more than 10 years experience on sitting in the cold all day long, with only summer clothes on. Like 0 to 5 Celsius, with only shorts on, not even socks. I am winter swimmer as well. I do that, because i can think a lot more clear in a cold environment, it is good for the brain. Granted in Greece there is not that much cold, maybe 1 or 2 months of 0-5 Celsius.

That can be achieved by putting music on, which speeds up the heart pulse. Usually hard rock, metal, thrash metal etc. In that case, the body starts sweating a lot, not matter the temperature. I combine that, with 5 simple exercises i do all day long which are important as well.

My point is that using music, someone can be in charge of his heart pulse. But my biggest complaint always was that these metal guys, are masters of the guitar, but other kinds of music have better taste in rhythm, in melody etc. Using programs like that we can evolve it a little bit, to be more pleasurable to listen.

I know about about binaural beats, i have tried to listen to different hertz for hours on end, they don't work in my opinion. At least in my case.

There's a real effect, just nothing even remotely close to the actual fantastical claims being made about it. It's highly doubtful there's some sort of profound way to induce arbitrary brain states through audio input alone.

I remember vividly that this was very hyped in some circles around 2005 or thereabout, with wild claims that listening to some strange white noise for twenty minutes could induce full-blown psychedelic trips even in people with no psychedelic experience. I even tried a bunch of em, and the only clear effect was a mild headache. And I was naïve enough to think it might work back then, and yet there wasn't even really a placebo effect.

I was thinking of a scenario of mapping our brain activity, like reading functions of some module, or a birthday party, or a business meeting. From then on, we put the machine to generate songs and activate roughly the same brain region of the actual life experience. We do that once, and generate 10 songs.

The next time that life experience takes place, we listen five or ten minutes to the relevant songs before it happens. We do that to put ourselves in the mood, as a mental preparation tool.

That's all. Not creating worldwide Britney Spears hits, or alter our consciousness. Just a mental tool.

Oh I see, you're essentially describing what I think of as aural contextual clues/associations. Sure, that's very real and I've experienced it first hand.

Though I'm sceptical how directed it can really be. There are some songs that have a bizarre effect on me for sure. Though most of the time it's because I had some strange experience involving the combination of said music with psychedelic drugs. And now the music can induce echoes of that experience. But it's just sort of an association that happened by accident.

I guess I could see people using this phenomenon in a more deliberate manner. And you certainly seem to be doing so. Though it could be that you're just somehow more able to than most people.

That happens in general, many people associate music with relevant actions of their life. They listen to songs which are more suitable to driving a car, or lounge beats to read books.

One scenario is to record some sounds of the event once, like the laughter of a child in it's birthday, put it to songs, and listen to it before the next time it happens.

One other scenario, is to record the brainwaves of some difficult task, like programming, and by listening to songs, try to activate the same region of the brain. When there is an automatic way to create one song which activates an area but not exactly, and another song which activates one more area but not exactly, the machine will try to figure out how to combine the two songs together which will hit the spot. It is essentially a problem of combining information, which A.I. statistical engines are very good at it.
