In this track, Hunter Hayes reflects on moving past a relationship that once held significant meaning. The lyrics describe the transformation of a once-loved song into something obsolete and forgotten, symbolizing the end of an emotional connection. Hayes uses musical metaphors to illustrate how he used to cherish and replay memories of the relationship, but now sees them as outdated and irrelevant. The chorus emphasizes his resolve to move forward, likening his ex to "yesterday's song"—a tune that no longer resonates with him. Ultimately, the song conveys themes of growth, closure, and embracing new beginnings while letting go of the past.
