Seattle singer and poet Mary Lambert is best known for writing and singing the musical element of Macklemore and Ryan Lewis’s gay rights anthem “Same Love,” a beautiful paean to marriage equality overlaid with Macklemore’s spoken word performance. She performed the song alongside Madonna at this year’s Grammy awards ceremony while Queen Latifah presided over a mass gay wedding. Lambert has also recorded an expanded version of the song without Macklemore’s spoken voiceover called “She Keeps Me Warm.”

Before becoming a singer, Lambert had some success as a spoken-word artist and poetry-slam regular in the late 2000s, and much of her music has that same sort of coiled, hurting, on-the-verge-of-tears feeling to it that is an important element of the poetry slam tradition. Her latest hit song, “Secrets,” is significantly more bouncy than “Same Love,” but no less heartfelt. She begins by listing personal traits that others might be ashamed to own, including her bipolar disorder, her emotionalism, her weight and her lesbianism. But she then embraces these labels, refuses to hide who she is anymore and says she doesn’t care if the world knows what her secrets are. “So what?” she asks with repeated, cheerful defiance. It’s such a positive, openhearted celebration of self-acceptance and tolerance. Shame? Self-loathing? Denial? We’re so over it.
