U-KISS Essentials

These Ubiquitous Korean International Idol Super Stars (their name is an acronym) have been one of South Korea's leading K-pop boy bands since their 2009 hit "Man Man Ha Ni." Backstreet Boys descendants who've starred in their own variety shows like U-KISS Vampire and Chef Kiss, the group woo young female fans—the so-called KissMe's—with a perky, multilingual blend of hip-hop, electro-pop, and R&B balladry. The underpinnings of their tracks can range from tough trap snares to strummed acoustic guitars, but their lush vocal harmonies are always silky smooth.
