Group T-ARA released their new song, "What Do I Do" today.

They used part of the original melody from the 1977 release of "What Do I Do" and made a 2013 version of it with the help of Shinsadong Tiger.

This song's choreography features a musical style as they show off the diamond step and other fun dance moves from that time period.

This song appeals to a wider audience as  it will bring back memories for the older generation and be a fun and quirky song for teenagers.

On the other hand, actor Son Ho Jun featured in the music video and hopes that everyone will enjoy the video.
