Because it is an approach to human’s fundamental desires and emotions, it does not work well just because the instrument is freaking good or musically superior.
For example, if you are the most popular artist, the person who won the classic contest is not that kind of thing. The same is true for songs, and it is not always good if they are good. However, some users are so impressed by their good playing and singing that they can not simply think.

On the other hand, some users say “I don’t know the song or something, but everyone is really cool”, so it seems to me that “After all, there is nothing to do with selling and the quality of the music.” But that’s not the case. Some of the coolness includes the goodness of the song. So, in this case, it seems to seek things other than music, and it is thought that the satisfaction of the mind is achieved by uniting with the music. If you really like cool people, you should be a model, but why are you going to a musician? It is thought that coolness is realized and satisfaction is achieved by the involvement of Otoya melody, rhythm, and various things.

So what kind of sound source, what kind of music, what kind of artist should it sing? It is the music business that thinks about that kind of moderation.
