Written at various stages over the past few years, Goodbye Lullaby is filled with appealingly relatable, heartfelt songs that convey a variety of emotions and reflect a bittersweet mood not generally associated with Lavigne’s best-known tunes. Except for the anthemic first single, the irresistibly feisty “What The Hell” and “Smile,” which create a perfect bridge from her previous work, the remainder of Goodbye Lullaby finds Lavigne exploring what it means to push through the tough times and emerge stronger for it — a theme apparent on songs like “Everybody Hurts,” “Push,” “Remember When,” and “Wish You Were Here.”
