What songs do you have on loop and why?

I used to play the song "Bamboo Horse" from the TV series "The Wrong Years in the Palace" for two months, probably because I was too involved in watching TV at that time. The song "Bamboo Horses" is a short song that expresses the helplessness of the Crown Prince and Nian Shuyuan, Princess Rongxian and Nian Juan Yao, and their hope that they will be born in a normal family in the next life. The song expresses the helplessness of Nian Jang Yao who could not love Princess Rong Xian, and the heartache of the Crown Prince and Nian Shuyuan who loved each other but could not keep each other, so what about the Crown Prince? What about the Crown Prince? What about the Crown Prince, what about the Princess, what about the General? Still can't escape the cage of fate. When I watched this drama, I really sympathized with Princess Rongxian and Nian Shuyuan, and I also cried a lot, so I really like this song, and I have a kind of immersive feeling.
