I have always wondered why sometimes the songs pushed by Netease can penetrate my heart, which is exactly what I want to hear, or the songs of my heart. Later, I made a rational statistic. In fact, in many cases, it is not allowed to push the sun back. A daily tweet may have only 1-2 hearts. Of course, unless the songs you listen to are not omnivorous, for example, if you only listen to classical music, the chances of pushing hearts are very high. For example, if you only listen to reggae music, the style of pushing is just what you like. Well, for omnivores, in fact, this kind of push is just "guessing boring." Is it allowed or not? It varies from person to person. I can only say that Netease is ahead of other software in this respect, I don't believe it.
