Why many people like to listen to old songs

I slowly discovered that everyone around me likes to listen to old songs, like the 70s and 80s, the style is very nostalgic, and it has a sense of age. It brings us back to that era in an instant, listening and listening to it. When the picture came out, the tears stayed unconsciously. Later, I found out that a little bit of time passed when I was growing up, and my memories of childhood became more and more blurred. Sometimes I occasionally saw the grandparents who joined and reminded me of the New Year scene when I was young. That is how happy and happy it is. Every family in the village began to prepare for the New Year, killing pigs, squeezing oil cake, and hanging lamps, but now they are deserted and rarely see that kind of scene again, and people have become indifferent and never come back. I like to live in a big city, and some of them show off their outside world when they come back. They are no longer innocent as they were when they were young. Sometimes I think if it can grow slowly, I really hope it is true. After all Our parents are getting older. Looking at their pale hair, I burst into tears. People always leave their homes to go outside, but I can't live without the warmth of my childhood.
