Hip-hop group MFBTY, consisting of Yoon Mi-rae, Tiger JK and Bizzy, prereleased a track from its upcoming album “Wondaland” on Monday.

Feel Good Music, the agency whose co-CEOs are the hip-hop couple Tiger JK and Yoon Mi-rae, made the surprise release of the track, three days ahead of the unveiling of the album slated for Thursday.

The track, “Bucku Bucku,” means shyness or awkwardness a person experiences with a crush, or when put under the spotlight.

Various hip-hop artists -- idol group BTS’ leader Rap Monster, husband-wife duo EE, Feel Good Music’s rookie Dino J -- participated in the production, expressing their own “Bucku” sentiment.
