“End Game” revolves around the idea of Taylor wanting to be her lover’s soulmate. While she never mentions who this person is, the Internet seems to be convinced that since he has a huge “reputation,” he must be Tom Hiddleston, whom Taylor was in a relationship in 2016, or Joe Alwyn, her boyfriend as of the song’s release. Through the lyrics, Taylor hopes that the “drama” revolving around her doesn’t keep this guy from being with her because they’ve already been so close.
Taylor previously worked with Ed Sheeran on her 2012 track “Everything Has Changed,” on which Ed sang the second verse. This is her first collaboration with Future and her overall third collaboration with a rapper, following the remix of her track “Bad Blood,” which featured Kendrick Lamar., and “Both of Us” by B.o.B., featuring Swift.
The track was released as the 3rd single off the album and sent to contemporary hit radio on December 3, 2017 in the United States. The music video was released on January 11th, 2018.
