The title track "Free Somebody" is an electronic pop dance track, with a future house sound. The lyrics describe the desire of wanting to help someone find their true self so they can freely live their dream.
"I Wish" and "My Medicine" were both written and composed by Luna. The lyrics of "I Wish" describe her hope that "young girls and young boys will never know the bitter taste of coffee and the dark side of the world". "My Medicine" is an "R&B ballad song with a warm and fantasy-like feeling" that Luna wrote for her mother.
The album had a moderate success in South Korea, selling over 10,000 copies in 2016; but Free Somebody was considered a refreshing and unexpected move from Luna's predominant image as a ballad singer, its electronic style resonating especially with international audiences.
