"music imprints on a person more than anything else", or something like that.
Well, I personally would add smell to that list, but they aren't wrong, with it being a matter of degree at worst. The people in the video suggest that music can bring somebody to organize around themselves and remember who they are.
This is striking, because I've long used music for exactly that purpose. When things get ugly, life messy, my head full, confused, or just worn, music can just wash that away, bringing memories and that sense of ME, potent, alive, ready to go again. I've been caught many times with headphones on, jamming to something I just crave, or that I imprinted on, my response when asked, "just remembering who I am"
So, that's just a happy alignment of things, nothing special, particularly on my part. What is very interesting is the idea that simple science, observation and study of people on more basic levels may well lead to some new ideas, suggestions on how they work, why they work, etc... So much of the world is right there in front of us, if we can only break down barriers, reach that little kid like state where it's all new and just observe first, think and associate later...
Damn cool discovery.
