K-pop quartet KARD returned late Saturday night (Sept. 21) with their new song “Dumb Litty.”

Out Sunday in South Korea (Sept. 22), the new single is produced by BM. An EDM banger -- literally, as it's propelled by aggressive beats and dynamic synths -- "Dumb Litty" features KARD's BM, Jiwoo, J.Seph, and Somin as they declare that they're not worrying about what others are saying and aren't going to stop doing what they’re doing.

“Dumb Litty” is KARD's second digital single and it was revealed through a powerful music video that reimagines the four members of the act as charismatic, classically-inspired gods, such as Thor, Athena, Aphrodite, Ares, Hera, and others from the Greek and Norse pantheons.

KARD, a rare co-ed group in the K-pop world, released their first single, "Oh NaNa" featuring Heo Youngji, in 2016 and have regularly seen songs land within the top 20 of the World Digital Song Sales chart. Their most recent song, "Bomb Bomb," peaked at No. 3 in April.
