Sara Bareilles' "She Used To Be Mine" Music Video Is A Beautiful Accompaniment To The Melancholy Song — VIDEO

On Friday, Grammy Award–nominated singer-songwriter Sara Bareilles premiered the music video for "She Used To Be Mine," the first offering from her forthcoming new album, What's Inside: Songs From Waitress (due out Nov. 6). According to Elle, Bareilles' much-anticipated fifth LP "will serve as the official soundtrack" for the stage adaptation of Waitress , a 2007 film starring Keri Russell. The 35-year-old "Love Song" hit-maker composed the score for the upcoming musical (which, according to Playbill, is expected to make its Broadway debut in April 2016), and said in a recent statement that she just couldn't "imagine handing over the songs ... before selfishly finding a way to sing them" herself.

"She Used to Be Mine" is an emotional piano-led ballad sung from the perspective of Waitress' main protagonist, Jenna. Jenna is trapped in a loveless marriage and hates her job at a diner. Her only joy in life? Baking pies. As the video opens, Bareilles sits in front of a large dressing room mirror and laments that she doesn't recognize the woman staring back at her. She sings: "It's not simple to say / That most days, I don't recognize me / That these shoes and this apron, that place and its patrons / Have taken more than I gave them."

Though she's changed in many unexpected ways over the years, Jenna still remembers her former self. "She is gone, but she used to be mine," the chorus sadly concludes. Later in the video, we're treated to scenes of Bareilles performing behind a piano — the spot where she truly shines. The simple black-and-white clip is the perfect accompaniment to the melancholy (but beautiful) song.
