As any Swiftie knows, Taylor expresses herself best through song, and her Lover album gave us even more rare glimpses into her personal life. While Taylor's Reputation album included tongue-in-cheek songs about her public persona, her Lover album was the complete opposite. Of course, there were songs about her romance with Joe Alwyn, but she also showed a more vulnerable side as she opened up about her mom Andrea's battle with cancer. She even touched on mental health as she talked about her overbearing anxiety in the album's prologue letter.
