"Roar" widens its lead at No. 1, while Lana Del Rey and Drake also move up.

Once again, Katy Perry's "Roar" makes the loudest noise on the Billboard Hot 100, as the song rules the survey for a second week, fueled in large part by the premiere of its video last week. Meanwhile, Lorde and Lana Del Rey & Cedric Gervais make notable moves within the chart's top 10 and Drake returns to the region.
 
"Roar" claims the Hot 100's top Streaming Gainer award, as it rises 3-1 on the Streaming Songs chart with a 122% increase to 12 million U.S. streams, up 33%, according to Nielsen BDS. The song's fun queen-of-the-jungle-themed video premiered on Thursday (Sept. 5). "Roar" leads the subscription services-based On-Demand Songs chart for a second week (2.1 million, down 1%).
 
"Roar" crowns Digital Songs for a fourth week, selling 373,000 downloads for the week ending Sept. 8 (down 17%), according to Nielsen SoundScan. (Last week, it gained by 14% in sales after Perry performed it on the MTV Video Music Awards [Aug. 25]).

Katy Perry's 'Prism' Album Preview: 10 Thing You Need To Know

"Roar" adds the Hot 100's top Airplay Gainer award for a second week, charging 6-2 on Radio Songs with a 28% spike to 123 million all-format audience impressions, according to BDS. How fast a start is the song off to at radio? It's the first to rocket to the Radio Songs top two in five weeks or less since 2004, when Usher and Alicia Keys' "My Boo" also reached the region that swiftly.
 
In all, the success of "Roar" so far bodes well for parent album "Prism," due Oct. 22. Capitol Records previewed the set on Thursday, with Perry introducing each track, for industry invitees at Solo in New York. "I'm beyond impressed. Incredible production and killer hooks," beamed WHTZ (Z100) New York program director Sharon Dastur of the album. Check out Billboard's review of the set here, as well as what other attendees had to say about "Prism."
 
"Roar" widens its lead tenfold atop the Hot 100 over Robin Thicke's former 12-week No. 1 "Blurred Lines" (featuring T.I. and Pharrell), which spends a second week at No. 2. "Roar" gains by 18% in overall chart points, while "Lines" loses 2% of its sum, granting the former title a hefty 42% lead in points; last week, the margin was 4%.
 
Still, "Lines" leads Radio Songs for a 10th week (194 million, down 5%). It's the first song to reach double-digit weeks at No. 1 since Rihanna's "We Found Love" (featuring Calvin Harris) led for 12 frames in 2011-12. "Lines" logs the longest Radio Songs command for a solo male since Lil Wayne's "Lollipop" (featuring Static Major) licked the competition for 10 weeks in 2008. (Goo Goo Dolls' "Iris" holds the mark for the most weeks atop Radio Songs: 18, in 1998.)
 
"Lines" slips 2-4 on Streaming Songs (4.9 million, down 26%) and 3-5 on Digital Songs (168,000, down 31%). Billboard's Song of the Summer links a 14th week at No. 1 on Hot R&B/Hip-Hop Songs and a 17th week atop R&B Songs.
 
Sixteen-year-old New Zealander, and current Billboard magazine cover act, Lorde blasts 8-3 on the Hot 100 with her breakthrough U.S. single "Royals." The track wins top Digital Gainer honors for a fourth time in five weeks, vaulting 8-2 on Digital Songs (225,000, up 34%). It reaches the top 10 on Streaming Songs (12-8; 4 million, up 40%) and lifts 17-13 on Radio Songs (72 million, up 26%).

Aided by its support at alternative radio, "Royals" rules Hot Rock Songs for a second week. It tops the Alternative Songs airplay chart for a fifth week, tying Alanis Morissette's "You Oughta Know" (1995) for the longest domination on the ranking for a song by a solo female.

Jay Z's "Holy Grail" (featuring Justin Timberlake) reaches a new Hot 100 high point, pushing 5-4. It jumps 7-4 on Radio Songs (103 million, up 16%), although it falls in sales (159,000, down 7%) and streaming (4.1 million, down 12%). It returns to the Rap Songs summit for a sixth week at No. 1 and, as previously reported, climbs to the top of the Rhythmic radio airplay chart.
 
Avicii scores his first top five hit on the Hot 100, as "Wake Me Up!" springs 7-5. It climbs 6-3 on Digital Songs (197,000, up 12%), 8-7 on Streaming Songs (4 million, up 8%) and 18-16 on Radio Songs (69 million, up 27%), the lattermost move spurred in part by the innovative dance/folk song's airplay at rock radio. On Dance/Electronic Songs, "Wake" is the new No. 1 after holding at No. 2 for two weeks.
 
Lana Del Rey & Cedric Gervais' "Summertime Sadness" soars 10-6 on the Hot 100, marking a new peak. The track reaches the Radio Songs top 10 (13-8; 81 million, up 8%), while returning to its peak to date on Digital Songs (11-8, despite a 2% decrease to 127,000). It backtracks 10-12 on Streaming Songs, although with a 3% gain to 3.1 million.
 
Lady Gaga regresses 6-7 on the Hot 100 with "Applause." While the lead single from "ARTPOP," due Nov. 11, jumps 31-22 on Radio Songs (47 million, up 19%), it slides 4-6 on Digital Songs (160,000, down 25%; like "Roar," it logs a retail decrease after it experienced a post-VMAs bump last week). On Streaming Songs, it descends 6-11 (3.2 million, down 25%).
 
Drake freshens up the Hot 100's top tier by tallying his 13th top 10, as "Hold On, We're Going Home" (featuring Majid Jordan) advances 12-8. The track sports gains on Radio Songs (15-12; 73 million, up 25%) and Streaming Songs (20-14; 2.7 million, up 17%). It edges 10-9 on Digital Songs but with a 10% loss to 127,000.

Drake's 'Nothing Was The Same': The Billboard Cover Story

After reaching a high of No. 8 two weeks ago, Capital Cities' "Safe and Sound" returns to the Hot 100's top 10 (11-9). 54% of its chart points are from airplay (the highest percentage of any title in the top 10 this week), as it bullets at No. 3 on Radio Songs (116 million, up 8%).
 
Closing out the Hot 100's top 10, Eminem's "Berzerk" tumbles from No. 3, where it debuted last week. It registers a 48% drop in sales to 187,000 (a not atypical second-week plunge for a song by a star act that makes a splashy sales start before airplay and streaming have yet to catch up). Still, the lead single from the rapper's album "The Marshall Mathers LP 2" climbs 59-49 on Radio Songs (26 million, up 24%). It drops 13-15 on Streaming Songs (2.6 million, down 3%).
 
Two songs depart the Hot 100's top 10: Miley Cyrus' No. 2 hit "We Can't Stop" (4-11) and Imagine Dragons' No. 3-peaking "Radioactive" (9-12). Following the record-breaking start for the video for Cyrus' next single, "Wrecking Ball," on VEVO, the ballad seems likely to vault toward the upper reaches of next week's Hot 100. Watch for details later this week on where the song could rank next week following the compilation of more building data.
