There is no "glitch". That is something pop stans tell themselves to make themselves feel better about their fave's songs not popping up. iTunes utilizes thousands of servers, so it's nearly impossible for someone to make the system glitch. The problem is simply that iTunes has yet to update, which is does randomly at times, or it's just not selling enough to chart at the moment. If it was charting, no "glitch" is keeping it from showing up.
