I'm not sure if I grasp the question as intended? Can you elaborate a bit more caesar?
Sure. According to evolutionary scientists, our mind is a system of organs of computation designed by natural selection to solve the kinds of problems our ancestors faced in their foraging way of life. This system boosts the likelihood that we will recall easily and quickly information about threatening or traumatic events, events whose recollection may one day be crucial, especially if our survival is challenged. If something important happens, we rehearse the events in our head or tell stories to others to help remember them. On the other hand, information that is not needed or is not important is rehearsed less. It loses its strength of recall as time passes. As more time passes, it becomes less likely that it will be used in the future, and we forget completely....
On the contrary, imagine if when remembering something - say a love song, sprung thousands of matches from our memory, requiring our mind to sort through and make sense of all of these entries. Mass confusion would result from the flood of the multitude of cues from this song. This data overload would likely have resulted in our ancestors being eaten by the saber-toothed tigers. So when it comes to memory, "less is more" (or forgetting) is probably a very good thing.
The problem then, of course, becomes that if we want to recall something "minor" (vs. life-threathening), we need to pay attention and voluntarily encode things to remember them. This takes a lot of effort. Say you are a business consultant meeting dozens of people in a room. One person who can give you valuable information and you need to meet with tells you his name is Baker. He happens to be pear shaped dude and with a dough-boy looking face. You make a conscious note of this image - and say Baker 10 times. Bingo! Chances are, you will remember him from the rest of the crowd.
Remembering how somethings sounds may be a bit more challenging from an imagery and repetition perspective. However, I am guessing that there are some folks here who are either manufacturers, reviewers, audio pros, or prolific gear swappers, who have come up with innovative encoding techniques of the songs they listen to on different gear.
