Cyrus's 'Bangerz' Hits No. With a blitz of media and constant online chatter, Miley Cyrus easily clinched the top spot on Billboard's album chart this week. "Bangerz" (RCA), her latest, opened with 270,000 sales, according to Nielsen SoundScan, becoming Ms. Cyrus's fifth No. 1 album, including three released under her Disney alter ego, Hannah Montana. "Bangerz" also tops the charts in Britain, Canada, Australia and Ireland this week. Ms. Cyrus, 20, has been perhaps the most unavoidable figure in pop culture since at least Aug. 25, when her hypersexed, tongue-wagging performance stole the show at the MTV Video Music Awards. She was widely ridiculed for it, but has remained in high demand. And Ms. Cyrus, 20, scored her first No. 1 single last month with "Wrecking Ball," which is currently the top video on Vevo, with 238 million views. MTV also ran a special about her, and she also won acclaim as a host of "Saturday Night Live." And her buzz wasn't hurt by being the topic of endlessly tweeted-about open letters from Sinead O'Connor, Annie Lennox, Amanda Palmer and even Sufjan Stevens. But for the last few weeks an unlikely figure has kept Ms. Cyrus from total domination of the pop charts. Lorde, a 16-year-old from New Zealand, has crossed from underground phenomenon to mainstream star with her song "Royals," which holds the No. 1 spot on Billboard's Hot 100 singles chart for a third week in a row. Last week, listeners in the United States downloaded "Royals" sold 294,000 times and streamed it 2.8 million times on services like Spotify and YouTube, according to SoundScan; it is also one of the most-played songs on pop radio stations around the country. ("Wrecking Ball," also getting heavy airplay, is No. Also on the album chart this week, the Las Vegas band Panic! At the Disco's new album, "Too Weird to Live, Too Rare to Die!" (Fueled by Ramen/Decaydance), opened at No. 2 with 84,000 sales, slightly more than Drake's "Nothing Was the Same" (RCA) which falls one spot to No. The rapper Pusha T is No. 4 with 75,000 sales of his latest release, "My Name Is My Name" (G.O.O.D./Def Jam), and Justin Timberlake's second album this year, "The 20/20 Experience - 2 of 2" (RCA), fell four spots to No. 5 in its second week with 70,000 sales, an 80 percent drop from its opening.
