One of Korea's most unique music artists, Zion. T has just released the song 'Those Days (without you)' for the Prison Playbook OST, one of the most unorthodox OSTs to ever be released. 'Those Days (without you)', is a smooth R&B track, and for anyone who knows him, completely in tune with the style of Zion. T that we have come to know and love. The track is yet another addition to Prison Playbook's fantastic OST, chock-full of great hip-hop and R&B songs; differing vastly from the standard ballad acoustic, and orchestral heavy ballad-filled OSTs that are most common. Zion. T is just one of those music artists that everyone should listen to and 'Those Days (without you)' is a perfect example as to why. Go and check out the music video now!
