Story behind a Song

A song, most broadly, is a single work of music that is typically intended to be sung by the human , but for a listener there are some songs through which he/she connects emotionally. Songs that are special to him/her. There are songs that are special to us and some behind which there is a beautiful memory.
The songs we love become woven into a neural tapestry entwined with the people, seasons, and locations throughout our lifespan. Listening to music engages large scale neural network across the brain, including brain regions responsible for motor actions, emotions, and creativity.
What seems to happen is that a piece of familiar music serves as a soundtrack for a mental movie that starts playing in our head. It calls back memories of a particular person or place, and you might all of a sudden see that person's face in your mind's eye. Now we can see the association between those two things—the music and the memories. Therefore the song becomes special and we tend to recall all the memories.
Sometimes it makes us happy or sometimes it gives us a bad trip.
We all are wanderers , similarly when we listen to a music it swings alot and recalls the memories, and then those songs become special to us.
Sometimes it's not the song that makes you emotional, it's the people and the things that come to your mind when you hear it.
