After the massive success of Lee Hyori's “U-Go-Girl” and Girls' Generation's “Gee,” producers E-TRIBE built a reputation for songs that combine catchy choruses with addictive beats. The duo has worked with some of the biggest names in K-pop, bringing its skill set to emotional ballads and dance-pop alike, and even created its own girl group, Dal★Shabet, to deliver more high-energy hits.
