It's been revealed that the members of T-ara cried tears of joy upon hearing news that their newest comeback track, "Day by Day", had conquered the digital charts!

On July 3rd, Core Contents Media revealed that "Day by Day" had ranked first on digital music sites such as Melon, Bugs, Soribada, and Cyworld Music immediately following its release. After the members were told of the great news, the girls were said to have gotten together in a group hug and cried tears of joy while practicing in their rehearsal room.

The song was originally scheduled for a digital release at midnight but was delayed to noon the same day.

The members stated, "We were worried because we thought the song would lose attention if we released it too late. We also stepped away from what you'd normally expect from a music video and produced it as a science-fantasy movie, so there was also some worry there. Fortunately, both the song and the music video have been receiving a lot of love. We promise to become a T-ara that pays back your love and support by working hard."

T-ara will be making their comeback through MBC's 'Show! Music Core' on July 7th.
