DOWNLOAD THIS: Perhaps the biggest takeaway on the singles side of the iTunes charts is this: Licking a sledgehammer and riding around naked on a wrecking ball is a smart career move, as the new one from RCA's Miley Cyrus unseats longtime champ Katy Perry's "Roar" (Capitol). Go ahead and tell us Miley's buzzing video hasn't played a role. Otherwise, Lava/Republic's Lorde, PRMD/Island/IDJ's Avicii, Interscope's Lady Gaga, Aftermath/Interscope's Eminem and YMCMB/Republic's Drake, among others, keep up the charge. On the album side, changes abound. XO/Republic's The Weeknd finds his vibey set at #1, while SYCO/Columbia's One Direction keep both the #2 and #10 spots for the deluxe and standard versions, respectively, of their latest, thanks to big pre-orders (Midnight Memories doesn't street until 11/25) . Other new arrivals include Capitol Nashville's Keith Urban, Def Jam/IDJ's 2 Chainz and U.K. chart hogs Arctic Monkeys (Domino). Stay tuned. (9/10a)
