sistar19 The SISTAR19 comeback is in full swing and people are digging it, and by people, we mean lots of people, because these ladies have climbed and climbed and climbed their way up the album charts. The single, "Gone Not Around Any Longer," has only been out for three days, and is topping Korean charts right and left. According to the Instiz iChart, the single holds the number one spot and is currently beating its second-place competition by over one hundred and thirty points. Not only that—the group's 2011 single "Ma Boy" is back on the charts. So basically, everyone loves them so much that they're revisiting old and new hits to satiate their appetite. WOW! Can SISTAR19 keep up the momentum?
