Katy Perry’s ‘Roar’ Dethrones Robin Thicke

On the music charts, summer may be ending with a “Roar.”

After 12 weeks as Billboard’s No. 1 single, Robin Thicke’s “Blurred Lines” â€" pretty much the song of the summer, despite a vote to the contrary by MTV viewers â€" has ceded its position to Katy Perry’s latest hit, “Roar,” which last week had 448,000 downloads and was streamed 2.1 million times in the United States on services like Spotify, according to Nielsen SoundScan. “Roar” is Ms. Perry’s eighth No. 1 hit.

Eminem’s newest song, “Berzerk,” had a strong opening this week, with 362,000 downloads. But because Billboard’s singles chart incorporates airplay and online streaming along with sales, Eminem’s track was held from No. 2 by the still immensely popular “Blurred Lines.” “Berzerk” opens at No. 3.

On the album chart, the Southern California rock band Avenged Sevenfold opens at No. 1 with “Hail to the King” (Warner Brothers), which sold 159,000 copies. Luke Bryan’s “Crash My Party” (Capitol Nashville), the top album for two weeks, falls to No. 2 with 92,000 sales. The next two rungs are held by new hip-hop releases: Big Sean’s “Hall of Fame” (GOOD Music/Def Jam) opened at No. 3 with 71,000, and Juicy J is fourth with 64,000 sales of “Stay Trippy” (Kemosabe/Columbia). Mr. Thicke is No. 5 with his latest album, also called “Blurred Lines” (Star Trak/Interscope), which sold 55,000.
