"Who Put This Song On?" is a young adult novel by Morgan Parker, published in 2019. The book follows the story of seventeen-year-old Morgan, an African American girl who is struggling with depression and anxiety. Morgan lives in a predominantly white town and attends a predominantly white school where she is often made to feel like an outsider. She copes with her struggles by listening to 90s hip-hop and R&B music and writing in her diary, which she calls her "Black Girl Manifesto."
As Morgan navigates high school, she faces racism, microaggressions, and ignorance from her peers and teachers. She also struggles with her identity and self-image, and the pressure to conform to societal expectations of beauty and behavior. Morgan's journey is complicated further by her religious upbringing, which clashes with her newfound beliefs and desires.
As Morgan begins to open up to others about her struggles, she discovers the power of friendship, love, and self-expression. The book is a raw and honest portrayal of the challenges faced by young African American girls in contemporary society, and the importance of finding one's own voice and identity in the face of adversity.
