During a Secret Session hosted by iHeart Radio, Swift revealed that the goal for the 10th reputation track was to make each session of the song sound like a move forward in a relationship – she also said that it’s something she’s been wanting to do for years, but finally succeeded with this song.

“King of My Heart” was first teased on October 26th, 2017, during Swift’s music video for her single “…Ready For It?”, where its song title was hinted at by a red graffiti crowned heart, which was in the background on a wall.

Taylor also makes other references to kingdoms throughout reputation, in songs like “Look What You Made Me Do” and “Call It What You Want.” However, the kingdom in which she refers to in “King Of My Heart” is definitely more intimate, just between her and her lover; personal and special.
