She Used to Be Mine was originally released by Sara Bareilles on her 2015 album What’s Inside: Songs from Waitress, as a single, and by Jessie Mueller on the cast recording of the soundtrack for the stage musical Waitress in 2016. It is about looking back on your life and regretting the changes that have occurred, but finding the strength to fight back and regain yourself. This is an incredibly expressive performance from Erin where she starts off mildly and builds in intensity through the song until the quieter ending, evoking the emotions that go with each section of the lyrics. The video has a beautiful, old-fashioned look, being in black and white with a soft focus, obvious vignetting and film scratches across the image which perfectly suits this performance, giving the impression of an impromptu performance from the character living the story.
