My conclusion is this. It is all about the moment. It gives us the privilege of submersing ourselves completely in a moment. In a world where our mind can be 100 different places at once, music can easily provide the opportunity, as a listener and creator, to be completely absorb by what happening right then and there. Your brain completely removed from the general clutter of your thoughts only to produce an emotion that is so incredibly real and true to that moment.
Put yourself on the dance floor, surrounded by great people, amazing atmosphere, and a tune comes on, that fucking tune that creates that feeling, that feeling where you think, is even happening right now. Your so in moment it barely feels real. But the reality is, that's what living in the moment is, being there and present to what is being presented to you in that instant. You aren't thinking about your bills, upcoming doctor appointment or even where you next meal is coming from, unless of course you smoked a big doobie before listening in on the music, in which case you might be half into the music and half entertaining thoughts of what might be in the fridge.
