Avicii, Lorde, Katy Perry Notch New No. 1s

Avicii rises 3-1 on Pop Songs with 'Wake Me Up!,' Lorde crowns Adult Pop Songs with 'Royals' and Katy Perry reaches No. 1 on Adult Contemporary with 'Roar'

Avicii, Lorde and Katy Perry roar to the top of Billboard's Nielsen BDS-based Pop Songs, Adult Pop Songs and Adult Contemporary charts, respectively, this week.

Avicii notches his first No. 1 on Pop Songs, as "Wake Me Up!" rises 3-1. The Swedish DJ had previously peaked at No. 33 last year with "Levels" and No. 34 in May with "I Could Be the One" (credited to Avicii vs. Nicky Romero).

Notably, "Levels" had brought Avicii's work to the summit in an uncredited role: it's sampled in Flo Rida's "Good Feeling," which topped the Feb. 18, 2012, tally. (That song also features the late Etta James with an unbilled vocal; meanwhile, Aloe Blacc is not credited for his vocal on "Wake.")

Avicii becomes the second core EDM act credited as a lead act on a Pop Songs No. 1: David Guetta reigned with "Without You" (featuring Usher) the week of Dec. 3, 2011. (Guetta also co-wrote and -produced the Black Eyed Peas' 2009 seven-week No. 1 "I Gotta Feeling.")

(EDM king Calvin Harris also scored a No. 1 on Pop Songs, as the featured act on Rihanna's "We Found Love.")

'ROYALS' RULES: Although it cedes the Pop Songs to Avicii's "Wake Me Up!" after a week at No. 1, Lorde's "Royals" lifts 2-1 on Adult Pop Songs.

And, now the obligatory mention of Lorde's age: with the New Zealand singer/songwriter turning 17 on Nov. 7, she's the youngest artist to reach No. 1 on Adult Pop Songs. She passes Avril Lavigne, who was 17 years, nine months and three weeks old when "Complicated" crowned the Aug. 3, 2002, chart.

'PRISM' PREVIEW: Katy Perry lands her highest debuts on Pop Songs and Adult Pop Songs, as "Unconditionally" starts at Nos. 19 and 26, respectively. The bow on the former chart was aided by airplay on all Clear Channel Media and Entertainment mainstream top 40 stations on Oct. 22, when the chain held an "iHeartRadio Album Release Party" for the arrival of Perry's album "PRISM" the same day.

The company branded the stations "Katy Perry Radio," with Perry serving as guest DJ, playing cuts from and offering insights on the album. The set is expected to debut atop the Billboard 200 this week with projected sales of 290,000. 

Meanwhile, first "PRISM" single "Roar" becomes Perry's second No. 1 on Adult Contemporary, where it rises 2-1. She previously led the week of May 28, 2011, with "Firework." "Roar" topped Pop Songs and Adult Pop Songs for five weeks each.
