(Disbanded In 2016.) 4Minute was one of the most popular groups in KPop for the past few years, going out on top with their powerful pop-hop monster hit "Hate" and giving 2NE1 a run for the title of most badass KPop girl group. But, perhaps the most notable thing about 4Minute was/is that it's Hyuna's group. Hyuna, considered one of KPop's sexiest sirens, has several "Best of KPop" songs to her credit, especially the naughty (by Korean standards) "Bubble Pop." Hyuna has been scene literally billions and billions of times on YouTube as Psy's female lead in "Gangnam Style."
