Although they released their "Blady 1st time Crazy Day" single late last month, rookie girl group Blady is only finally making their debut on today's episode of Mnet's�'M! Countdown'. Their title song "Crazy Day" is a retro dance track that possesses a repetitive melody that's easy for fans to follow along with. Choreographed by Main Spirit (who's also in charge of singers like Lee Hyori and Bada)�their dance moves were kept simple, but had charming highlights that spotlighted each member's individual style. Check out their debut stage below!
