With these remixes, T-ara will be targeting not only various music charts but actual clubs in Korea as well. The released remix tracks will also be uploaded on to Beatport, the largest music store for DJs in the world.

With "Sugar Free," T-ara made a complete transition from being known as a cute female idol group with choreography that is easy to follow to a charismatic femme fatale group.
