The Billboard Hot 100:
-- Katy Perry: Spurred by the premiere of its out-of-this world special-effects-heavy video March 31, "E.T." spends a second week at No. 1. The fourth Hot 100 leader from "Teenage Dream" surges by 29% to 327,000 downloads sold, according to Nielsen SoundScan. On Hot 100 Airplay, the song bounds 10-6 (88 million audience impressions, up 20%, according to Nielsen BDS).
-- Rihanna: As it holds at No. 2 for a second week on the Hot 100, "S&M" becomes her record-setting fifth consecutive No. 1 (2-1) on Hot 100 Airplay (and eighth overall), besting streaks of four each by Destiny's Child (2000-01) and Usher (2004). Rihanna has linked leaders in each of her last five appearances on the list courtesy of "Rude Boy," Eminem's "Love the Way You Lie," on which she guested, "Only Girl (In the World)" and "What's My Name?," featuring Drake, prior to "S&M." Her eight Hot 100 Airplay No. 1s break a tie with Usher for second-most toppers after Mariah Carey (11) since the chart first appeared in the Billboard issue dated Dec. 8, 1990 (when Carey's "Love Takes Time" held the top spot).
-- Adele: The first single from "21," which logged three weeks atop the Billboard 200 and has sold 941,000 copies in its first six weeks, becomes the soulful British singer/songwriter's first Hot 100 top 10 (17-10). The track shoots 11-9 on Hot Digital Songs (122,000, up 16%) and 50-36 on Hot 100 Airplay (33 million, up 35%). It spends a 10th week at No. 1 on the Triple A airplay chart, matching Sarah McLachlan's 1997 song "Building a Mystery" for longest reign by a solo female in the list's 15-year history.
-- Lil Wayne: After debuting last week following four days of sales, "John," the John Lennon-referencing second single from "Tha Carter IV" (due May 16), zooms 57-22 on the Hot 100 and 39-10 on Hot Digital Songs (116,000, up 134%). The set's lead track, "6 Foot 7 Foot," peaked at No. 9 upon its debut Jan. 1.
-- Sara Ramirez: Of the Hot 100's six debuts this week, two belong to TV-related acts. "Grey's Anatomy" actress Sara Ramirez's cover of Brandi Carlile's "The Story," from the "Grey's Anatomy: The Music Event" soundtrack, which features songs from the ABC series' special musical episode last Thursday, begins at No. 69. The set starts at No. 24 on the Billboard 200, while Ramirez's own self-titled EP enters at No. 37. Meanwhile ...
-- "Victorious" Cast: ... Unlike the "Grey's Anatomy" ensemble, the "Victorious" cast offers regular musical performances on its Nickelodeon series. The troupe bows at No. 83 with "Beggin' on Your Knees," featuring Victoria Justice. The cast reached No. 50 in January with its prior chart entry, "Freak the Freak Out."
-- Chris Brown: Typical second-week erosion of a non-single from a top-selling album explains the 26-90 Hot 100 plunge for "Next to You," featuring Justin Bieber. After it debuted last week with 113,000 downloads sold, the song decreases by 77% to 26,000. Brown's "F.A.M.E." opened atop the Billboard 200 last week at No. 1 with 270,000. This week, the set slips to No. 4 (91,000, down 66%).
The Billboard 200:
-- Britney Spears: No doubt the biggest news on the Billboard 200 this week was the arrival of Spears' sixth No. 1 album, "Femme Fatale," with 276,000 sold according to Nielsen SoundScan. Four more new arrivals bowed in the top 10, with Wiz Khalifa coming in second place with his major-label debut "Rolling Papers" (197,000).
-- Elton John / Foo Fighters: John's "Rocket Man" greatest hits set re-enters the chart at No. 45 (up 458%) following his double-duty turn as both host and musical guest on "Saturday Night Live" (April 2). Meanwhile, Foo Fighters' "Greatest Hits" album (No. 47) returns after an Amazon MP3 daily deal on April 1 (up 482%).
-- "Tangled" Soundtrack: Following the hit film's DVD release (March 29), its soundtrack takes a colorful 382% leap back onto the tally at No. 63 with 10,000 sold last week -- its second-best frame, next to only Christmas week of last year.
-- Carrie Underwood / Brad Paisley: Like Paisley's "Hits Alive" -- which has the chart's largest positional gain, flying 65 spots to No. 98 (up 62%) -- Underwood's "Play On" takes an Academy of Country Music Awards-fueled increase (up 57%, a re-entry at No. 164) following the April 3 broadcast.
-- Celtic Thunder: It's not terribly surprising that Celtic Thunder's "Heritage" has the Billboard 200's biggest drop this week, falling 133 rungs to No. 173 (down 70%). Anything Celtic or Irish-related tends to perform well around St. Patrick's Day, but then falls apart soon after.
-- Fantasia: After the former "American Idol" champion returned to the show's stage last week, her "Back to Me" album sees a 45% increase and re-enters at No. 186. The song she performed, "Collard Greens & Cornbread," sold 3,000 downloads, up from basically nothing the week previous.
