Every time it rains, I will think of Jay Chou's "It Rains All Night" and Xu Song's "The World Is Cooling." The prelude of rustling footsteps on the road perfectly matches the rainy scene. But Xu Song's "Global Cooling" is not about the rainy environment, but about the human heart. This song is from the Sleepwalker album. It is easy to tell that this album is a song in which Xu Song thinks about social phenomena and criticizes some unhealthy tendencies or unpredictable people in society. Global cooling is aimed at the indifference between people, who no longer have good intentions, and are no longer willing to express their kindness and smile. We hope that we will not wait until everyone is indifferent to realize that the world is no longer so beautiful. Don’t wait until the world gets colder to realize something is wrong. The meaning of the lyrics is very intuitive, that's what it means. As for the other meaning of calling for environmental protection and hoping not to promote global cooling, I don't really agree. The lyrics don't write anything about the earth's environment at all.

So from the arrangement point of view, Xu Song did all the lyrics and music, and he was not the arranger. Therefore, from the style point of view, electronic elements were added. Looking at Xu Song's previous albums or music, there are very few of these elements in it. Xu Song's style is mostly It has a lazy singing style, so it is not suitable for adding fast-paced electronic elements. However, the global cooling is just as imagined. It maintains a moderate speed with looping drum accompaniment. The electronic elements do not dominate, but only in the chorus. Slightly added places can be regarded as a means, and it can be regarded as the most suitable combination for Xu Song. If you want fast-paced electronic music, I think it is difficult for Xu Song to adapt. Although the recent ones such as Best Singer have electronic elements, But I think the tuning is better. The style is like Li Ronghao's Li Bai Model, which is a jazz style. The treble part of the voice is particularly obvious. Therefore, if Xu Song wants to try fast-paced electronics, he needs a good tuner to make fine adjustments. Otherwise, I'm afraid. Xu Song is used to the lyrical and gentle series and is not suitable for this kind of singing. Although he does these songs very well, they are not his mainstream style, but Xu Song himself said that he will try various styles, so he is also making progress.
