80% of the old songs being listened to are enjoyed because of the memories they have attached to the song
Most of these old songs that we listen to take us far back to the happenings that was concurrent in our life at that point in time an example is a love song, when a particular love song is being played during a time you are deeply in love with someone it goes to a part of your brain and stays there, and when there is a heart break 💔 and the song is played the listener listens to that same song and he or she begins to remeniece and perhaps feel sad when he remembers the good old days, the hurt and the heart break .
Also it is save to say that so go down with depression and never come out of such antecedent for a long time , this is because the more they listen to that song the more they miss and would like to replay and go back memory lane .
