Gashina

"Gashina" is Sunmi's first release since the disbandment of Wonder Girls and the expiration of her contract with JYP Entertainment.

It was released as the lead single from her second Korean-language EP Warning.

Written by Teddy Park, Sunmi, Joe Rhee, and 24, the song was described as a "dancehall-style synth-pop number that rocks an Eastern-style atmosphere and a distinct rhythmic bass sound".
