I think these subliminals and binaurals are snake oil. Just look at those ridiculously specific purposes. There are different tracks that are supposed to he help you with specific
genres of video games, some are supposed to feel like certrain drugs or help you with headaches. How do they even come up with this stuff? There are also a ton of commercially available tracks with ridiculous claims and that's sort of a red flag.
However I do think they can have meditative effects or even provide pleasure. If you listen to static for some time you will have better focus after that. Meditation works and that's scientifically proven.
And for the pleasure part: I tried
this several times (got the pirated original track though, don't know if YT's compression fucks it up). I was lying on the bed and it was quite relaxing. Towards the middle I got a tingling sensation. And at the end when the sine wave part starts it got more and more intense. It felt really good. And it sound stupid but when the sensation peaked it almost felt like an actual orgasm. Only not originating from my dick but more like the whole body. Not quite as intense but very close and longer. At little bit like the moment before you ejaculate when jerking off. I can replicate it and sometimes it works better and sometimes not.
It's like when you listen to certain types of music. Like indie rock or whatever. You may like the song but those nice "soft beats" feel like a massage for your brain and that's when you feel pleasure. Only with this it's a little better because they're more build-up.
So in my opinion those things are only decent for meditation and relaxation. And most of it is scam and placebos. But it would be nice if someone has scientific sources on that matter.
