“I pushed myself and didn’t hold back,” Lavigne says of Goodbye Lullaby for which she wrote or co-wrote every song, and wrote and produced two — “4 Real” and “Goodbye” — entirely on her own. “I allowed myself to be vulnerable. I think it’s during the real moments that people can relate the most. Those who have heard the album have had very strong emotional reactions to the songs, so I realized that when something is so real, it will probably touch somebody. The beauty of music is that it’s open to interpretation.”

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.”

“Overall, the album is about how we all go through difficult experiences, whether it’s ending a relationship, losing a job, or just missing someone,” Lavigne says. “We get through it and we grow.” Nowhere is this feeling better expressed than on “Goodbye,” a delicate piano-and-string ballad that closes out the album. “’Goodbye’ is the most raw and vulnerable track I’ve ever written and recorded in my career,” Lavigne says. “It’s a very special song because I wrote and produced it myself. It’s so real and truthful. You can’t fake that.”

Goodbye Lullaby’s intensity is balanced out by its instrumentation: bright, rich textures of acoustic guitar and piano, as well as an orchestra on “Darlin’,” “Remember When,” and “Goodbye.” Through it all, from the upbeat pop tracks to the mellower ballads, Lavigne’s voice is front and center, summoning up and soaring easily through the emotion that her lyrics require.
