Launching their weekly promotions for their comeback song I Go Crazy Because of You and follow-up track�I'm Really Hurt, girl group T-ara held down the stage at M.net M! Countdown. Coordinated in sky blue outfits with orange and pink stripes this time, the sexy six performed their comeback song with strong energy and charismatic stage presence. What was special about this performance was the addition of the glow-in-the-dark accessories. The lights would dim during the chorus of the song, accentuating the neon color worn by each member. While I Go Crazy Because of You may have been lipsynched, the girls http://www.youtube.com/watch?v=NYA1JlIid6M T-ara also performed their follow-up track, clad in white suits and hats. The catchy choreography is almost as addictive as the song itself. I know I'm tugging my invisible tie every time I hear I'm Really Hurt. http://www.youtube.com/watch?v=kcelODFiRsY
