Why is it single cycle?

What is the most repeated song in your single? Why? Thank you for inviting me! This question is very interesting, because the answer to this question is not clear in a few words. In the long life, everyone has different experiences, different living environments and different social experiences in different periods, which will create different personal orientations and preferences. For example, I like listening to songs for a while, and I like listening to other songs for a while. People in every era listen to different songs, which will reflect the characteristics of his era. Take the music I like to listen to at the age of 60 as an example: when we were students, there was no tape recorder, no TV series and no computer, so there would be no "single cycle". The songs I often listen to are Dongfanghong, Chairman Mao's words are in my heart (tunnel warfare episode) and My Motherland (Shangganling episode). I remember my brother can play "Chairman Mao's words are in my heart" on the flute, and I also learned to play this song with my brother. Speaking of which, my brother is still my first teacher. It's a pity that my brother will never play another song, and he will only play this song after many years. I am better than my brother in this respect. When I was in middle school, I remember that the school assigned a female teacher named Yue, who was our Chinese teacher and our head teacher. Because of her young age, she is responsible for the propaganda work of the school and plays gymnastics music on the radio. After getting up every morning, doing exercises at noon, and after school in the afternoon, the school tweeter will play "Old Landlord Check Shop", which will be played over and over again (at that time, it should be a phonograph, which can only be played over and over again manually), and everyone will take pains to listen to it, so that many students in the school will sing this song. After many years, it is still nice to hear this song occasionally, and I can still remember the scene at that time. When I first started working, I had a phonograph and many records. I often listen to youth league songs, the red sun shines on the frontier, Hong Hushui, making waves, taking Lei Feng's gun, the song of Karamay, Chairman Mao sending people and so on. Not a single cycle, of course. Put a record at the end and then change it. Later, after the Korean film "Flower Girl" was released, the songs we often listened to were episodes such as "Flower Girl"; After the release of the Indian film Wanderer, the streets and alleys were filled with "songs of Raz" and "songs of Rita". After the Japanese film Chasing, Song of Du Qiu was all the rage. These classic songs are still in my computer, and I occasionally open them to enjoy them. I am not afraid of jokes. As an old antique, I have a special liking for the local operas in China. If my single is a treasure of our Chinese nation, it is a local opera. I like the aria "My mother, sit down" in the Henan opera Chaoyanggou. I also like the aria of Xiao Cangwa's Xie Jie in the opera Xi Juan Pass. I also like the aria "betrothed to the Zhao family since childhood" in the movie.
