iTunes U.S.

DOWNLOAD THIS: The iTunes singles Top 10 remains fairly static, with a few tracks threatening to bust in (notably "La La La" by Capitol's Naughty Boy f/Sam Smith, at #11 as we post this). On the album side, Frozen rules on, Shakira hovers at #2, Sony Legacy's Johnny Cash set from the '80s looms large, The Black Keys' new one (on Nonesuch via WB) breaks out and the EP by Capitol's Five Seconds of Summer ramps up ahead of street date.
