Talented male vocalists Kim Bum Soo and Kim Tae Woo are currently battling it out with their OST releases.

On the pilot episode of SBS's 'A Gentleman's Dignity', which aired on May 27, viewers were introduced to the theme song "High High" by Kim Tae Woo. Kim Bum Soo, on the other hand, lent his voice for the theme song, "Callus", of the drama 'The Chaser'. With the voices of the power vocals behind them, the songs are currently going toe-to-toe at the top of the music charts.

As of the morning of May 29, Soribada's real-time chart listed Kim Bum Soo's "Callus" at #3 and Kim Tae Woo's "High High" at #4. "High High" is a fun song that matches the bright, cheery story of the drama, while at the same time, drawing out the charming qualities of Kim Tae Woo's voice. "Callus" is a ballad song created by Yoon Il Sang and Yoon Sa Ra, who also wrote Kim Bum Soo's other hit OST, "I Miss You". The sweet strings and lyrical melody bring out the sad, plaintive tone of Kim Bum Soo's voice.
