Girl’s Day’s leader, Sojin, and One-Two’s rapper, Song Ho Bum, both participated in the upcoming third album of composer Kwak Tae Hoon.

Their project song is titled “Bum Bum Bum” and should be sweet and light for the summer, adding to the airy feel that one experiences during the summertime.

Listen to the joint project together! Do you think it captures the summertime feel?
