iKON, who recently made a comeback with New Kids: Begin, guested on the May 29 broadcast of SBS Power FMs 2 OClock Escape Cultwo Show.
After talking about member Chanwoo sharing the same name as DJ Jung Chan Woo, they introduced their new title tracks B-DAY and BLING BLING. They also discussed their new English stage names (Donghyuk as DK, Chanwoo as Chan, etc.), which were given to them by their agency representative Yang Hyun Suk. Donghyuk explained that his name DK came from the first and last letters of his romanized name, but Junhoe revealed that the members wanted to make it stand for dancing king since hes the best dancer of the group.
