The songs that Zhao Youyue had uploaded on NetEase Music were not really that popular. She was not a professional singer. She did not have the backing of an entertainment company that could help to edit and enhance her songs. Moreover, she had not attempted to promote her songs through various means. The most she did was to mention it during her live streams.
There are always lazy streamers. Some of them would even think this way: Since I have already heard all the songs during the live streams, why should I bother going through all the trouble to get on NetEase Music just to hear them again?
However, compared to songs that are sung during live streams, songs that are recorded properly in a recording studio tend to give off very different feelings. The latter would be better-suited for someone to quietly listen to when they are alone. This is why a lot of people would experience all sorts of joy when they listen to Ah Yu's songs on NetEase Music!
