Famous producer Kim Chang Hwan finally debuted the fruits of three long years of labor on today's episode of 'M! Countdown'! His very own boy group, N-Train, held their debut showcase on May 25th and revealed that they were determined to be acknowledged for their vocal talents alone. Their debut track, "One Last Cry", is a soul jam with lyrics about a man reminiscing over a woman who he can't seem to forget. N-Train explained, "Idols are usually known for releasing dance tracks with strong beats. We hope to differentiate ourselves by emphasizing an R&B style. We're confident, but we won't let it get to us, especially since we still have much to learn in order to grow as artists who leads Korean music."
