• Here, Morgan Wallen reflects on how he gave into temptation and hooked up with a girl. The whiskey he bought for her, the late-night phone call he took from her, the drive to her place all "shoulda come with a warning." If only there had been a sign, it might have prevented him from heartbreak.
• Morgan Wallen first teased "Warning" on an Instagram post on May 1, 2020. He uploaded a video of an acoustic performance of just him and his guitar singing the song, and asked his fans whether he should record it for his sophomore album.
