Girls' Generation's new unit HRS will release its debut digital single, "Skibidi," on Aug. 31, its agency SM Entertainment said on Saturday. The single will contain two tracks — the title song "Skibidi" and "Lowkey in Love." "Skibidi" begins with house music before shifting into hip-hop, with lyrics carrying the message of forging a new path together, SM said. The Girls' Generation-HRS was formed through Girls' Generation member Hyoyeon's personal YouTube channel, "Hyoyeon's Level Up," and includes Hyoyeon, Yuri and Choi Sooyoung.
