This is the first OST of the KBS Performing Arts '' Mind of the Heart '' based on the webtoon '10th Anniversary of the Year', which is based on the sound of the heart. The third group, MFBTY, a mixed group of Yoon Mi-rae, Tiger JK, I came up with a project.

This OST "My Own Voice" is an attractive song with a simple and dreamy melody based on hip-hop, R & B, and Future bass, and the powerful rap of Tiger JK and the vocals of Yoon Mi-rae catch their ears. Especially, the chorus, which starts with "You can hear your own voice," is causing infinite repetition with addictive lyrics and melody.
