"If I Die Young" is a mid-tempo tune accompanied by acoustic guitar, banjo, accordion, mandolin, fiddle, electric bass, and drums. It is in the key of E Major. The song is about the sadness of dying young as the narrator describes how she never really got to experience love and worrying about how her loved ones will miss her and deal with the loss. She recognizes that once someone passes away, others seem to pay more attention to that person's life: "And maybe then you'll hear the words I been singin' / Funny when you're dead how people start listenin'." She states that if she dies young, then her family left behind should "save their tears" for a time when "they're really gonna need them." She states that she has had a well-lived life in the line "Well, I've had just enough time."
Critical reception
The Band Perry received at least one letter in response to the song. In its envelope, the members also found a necklace with a ring on it. The letter's author was a young girl who had recently lost her best friend to cancer. Mourning her friend's death, the girl was contemplating suicide. Driving from work one day, she heard "If I Die Young" on the radio. Hearing "so much life in the song", the girl changed her mind. In her letter to The Band Perry, she wrote about the necklace: "I'm sending this to you, because it's the most important thing I own. This song literally saved my life."
Critical
Bobby Peacock of Roughstock spoke positively of the lyrics, saying that they were "very well-developed with interesting little details." He felt that, although the topic is "a little sugarcoated", the vocal performance is a "pleasant listening experience".
