“A Change of Heart” details the stages of falling out of love with someone. When the infatuation fades, you see them for who they truly are, and not who you thought they were.

It premiered on February 22nd, 2016 during Annie Mac’s Hottest Record on BBC Radio 1. Drummer George Daniel defined the “narrative” song as being by far “the most simple song” on their sophomore record. Frontman Matty Healy described it as a “pure ballad”:

It’s such a simple song – three notes – and the truth. We wanted it to [have] serious conviction. It turned into a very atypical “1975” song, being very sentimental, very self-aware, and as beautiful as we can make it.

The song incorporates concepts and lyrics from three older tracks by The 1975: “The City,” “Robbers,” and “Sex.” The official lyrics were confirmed through the band’s Twitter.
