It is that song that conforms to the listener's current mood and produces the sound of * * *.
People who listen to songs just feel good and have a special feeling. When they are tired of listening, they can stop.

Extension: single cycle.
Most of the people suffering from monocytic diseases are young and middle-aged white-collar workers. They have long-term insomnia symptoms, and it is always difficult to sleep at night or in the early hours of the morning. So they listened to the same song again and again until dawn, found a delicate balance in the "noise", and then fell asleep.
The single cycle is a manifestation of sub-health of urban white-collar workers. People with one-cycle disease can't control their emotions and prevent themselves from repeating themselves, but one-cycle disease is not necessarily a disease. We should actively adjust our mentality and treat our behavior correctly.
