Carpenter's "Yesterday Again", this song has kept me circulating for a long time. Until now, I still often cycle this song with a single, and every time I listen to it, it makes me feel as if I have returned to the distant past.

This song is used to recall yesterday, those past years, those past people. The carpenter's brother and sister sang in a low voice the nostalgia for the past and the feeling of time passing. Every time I listen to them sing, the feeling of time and space disorder seems to go back to the past and see my beloved again.

There are also Eason Chan's songs "Man on the Moon", "Forgotten Butterfly" and "Thank you", especially "Forgotten Butterfly", which is a sad feeling. Eason Chan's voice is not pleasant to hear, but he sings with great emotion, which can make everyone who listens to him enter the scene where he sings. His songs are so infectious that he never gets bored listening to them.

There is also Jay Chou's Agreement of Dandelion, Rainbow and Qilixiang, especially the sentence "And I can't tell whether you are friendship or missed love" in the Agreement of Dandelion. How many people have expressed regret, and how many people have recalled their youth.

And Vae's song "Love Your Past". The person who asked me to sing this song to her has long since left me.
