It's a Girls' Generation world, and we're all living in it. Or so it seems these days, as the ladies continue their elevator ride to dominance. "I Got A Boy," the hit single you've more than likely heard by now (and heard more than once), has shot up the Billboard charts.  The single managed to rank #1 on the World Album Chart, #2 on the Heatseekers Albums, and #23 on Independent Albums.  Certainly not shabby in the least. Can the girls keep up the momentum as the new year unfolds?
