"Shouldn't" was written by Jay Chou and written by Vincent Fang, and was included in the album "Jay Chou's Bedside Story" released by Jay Chou in 20 16, which was also the theme song of the TV series "Fantasy City" in 20 16.

In 20 17, Shouldn't also won the top 20 global pop music golden melody awards in 20 16. Jay Chou and May sang in concerts many times, but Jay Chou felt it was a pity to sing only in concerts, so Jay Chou specially wrote this song "Shouldn't" to promote their cooperation.

It shouldn't have been first published by Jay Chou and May. The two deeply interpreted the sad love in the song, and the song with their moving voices presented a beautiful and sad artistic conception.

Creation difficulty:

In order to write this duet love song well, Jay Chou thought about how to coordinate the range of two people and how to soar the melody. Jay Chou and May, who are working together for the first time, are very demanding and picky about songs.

When two people are singing, in order to achieve the feeling that the other person wants, they have been singing and constantly adjusting, hoping that the work can reach a perfect state.
