Sweetune (Hangul: 스윗튠) is a South Korean music producer team, originally consisting of Han Jae-ho and Kim Seung-soo, and now including nine other members. They have produced many hit songs and albums for Korean pop idols and Japanese idols, including Kara, Rainbow, Infinite, Nine Muses, Boyfriend and Spica. Sweetune is known for their 1980s-style synthpop and disco sound.
The Sweetune team includes music producers, composers, songwriters and engineers.
Before debuting with Spica, Kim Boa worked for Sweetune as a vocal coach, and also recorded background vocals and guide vocals. In 2014, three team members (Lee Joo-hyung, Hwang Hyun and G-High) left Sweetune and formed their own music production team, MonoTree.
