Just BLAQ is the debut EP by the South Korean boy groupMBLAQ. The EP was released online on October 14, 2009. The debut single, "Oh Yeah" was released the same day to Korean music outlets. The song "G.O.O.D. Luv" was released as the EP's second promotional single. The album is labeled as a single-album (single or maxi single) in Korea, however, the album falls into the category of an EP (extended play or mini album), and technically does not qualify as a single.
"Oh Yeah" was released officially on the 13 October 2009. The music video was choreographed by producer and mentor, Rain. The boys performed a Japanese version of "Oh Yeah" during a promotional trip to Japan. The Japanese version was only sang live, and there is no word if a studio version exists or if there are any plans to release one.
"G.O.O.D. Luv" is the single-album's official second single. During the film of MBLAQ's reality show "Mnet Art of Seduction", the boys took sometime to make their "own" music video for the song. The video was filmed with television cameras and cam-cord cameras. An "official" music video for the single was released on 10 December 2009.
