iTUNES CHARTS: On this Friday morning, there’s Magna Carta Holy Grail and then there’s everything else. But three members of the trailing pack bear singling out: KidinaKorner/Interscope’s Skylar Grey, whose debut looks fetching in the second slot; R&B diva Ciara, who’ll give Epic its biggest debut in some time; and alt-rock warhorses Pearl Jam, whose latest—this one going through Republic following the previous DIY release —just went up for pre-order. On the singles side, there’s Jay-Z again, putting up what appears to be a serious challenge to Robin Thicke’s gargantuan “Blurred Lines,” with Justin Timberlake in a significant co-starring role. The next time we take a peek at the singles chart, JT may well be there on his own with "Take Back the Night," the soon-to-be-available first track from the second 20/20 set. Thinks are nuckin' futs right now, boys and girls, in a good way. (7/12a)
