John Legend made a special cameo as himself in the season four Winter premiere of This Is Us, and we can't get his new song out of our heads. The heartfelt ballad, titled "Conversations in the Dark," is all about falling in love, which is pretty fitting seeing that the NBC series includes some epic love stories. "I won't ever try to change you, change you / I will always want the same you, same you / Swear on everything I pray to / That I won't break your heart," Legend sings. Look, I may not even be engaged yet, but I want to walk down the aisle to this song. Along with the single, Legend released a lyric video featuring footage of elderly couples in love. Listen to the full version of his song ahead, and get ready to swoon.
