After revealing a new concept for their repackage album titled Breaking Heart, T-ara teased us twice with their MV teaser of their new title track I Go Crazy Because of You. Shortly after the second teaser's release, T-ara's full title track and another track titled I'm Really Hurt was released. Today, the girls finally performed their comeback stage for the first time on Mnet's M! Countdown, performing I Go Crazy Because of You. Although they lipsynched for the most part, T-ara delivered a visually entertaining show that boasted their sexy dance moves and charismatic stage presence. The chairs as props were a hot addition to the performance as well.
