After releasing their teaser last week and their single album a few hours earlier, rookie girl group SISTAR has now released their title song MV, Push Push. With a colorful funky concept and a catchy track produced by the Brave Brothers, the SISTAR girls have certainly got the ingredients to go far. They will begin their full-fledged promotions starting with Music Bank on June 4th. http://www.youtube.com/watch?v=_GfZTYrLqZ0
