Since 2008, Junggigo had been quietly turning out groovy R&B tunes that showcased his smooth voice and easy falsetto. Then, in 2014, his flirty duet with SISTAR's Soyou, “Some,” became the No. 1 song in South Korea, which established him in the public mind as The “Some” Boy. While this success made him an overnight sensation, he's stayed true to the polished sound he started with, with occasional hits of funk or a breezy café vibe.
