"Army", which was chosen as the single because it was used in an advertising campaign for ITV in the UK, is a very safe song. .a signature pop song that follows the box office formula of “Love Me Like You Do”, its soft string/piano sound, and lyrics about friendship with close friends, completes the power ballad that is sure to be on a pop album. .however, never too emotional. Overall, while maintaining a calm tone, the sudden control that appears at the right time is great..
