Duets are definitely the new trend. K-Pop is ringing with dreamy harmonies of talented artists' collaborations; these duet songs have been successful on music charts as well.

The overwhelming trend seems to be the collaboration of female singers and male hip-hop musicians. Leessang's Gary met with Jung In to reap a harvestful with "Your Scent", released on May 27. The song swept music charts and is still currently in top tiers.

Another example is hip-hop musician San E and After School's Raina. With release of duet "Midsummer Night's Honey", the duo has presented fans with sweet performances.

In contrast, collaboration of talented vocalists also grabs attention. Davichi's Lee Hae Ri joined 4Men's Shin Yong Je as part of composer Choi Gyu Sung's "Acoustic Project", releasing "Your Empty Place".

Meanwhile, The One and Sonnet Son also returned on June 19 to release duet "Wistful".
