Chart Moves: Demi Lovato Leaps To No. 1 On Mainstream Top 40 Chart

As previously reported, Flo Rida's "Whistle" returns to the top of the Billboard Hot 100 for a second week at No. 1, pushing Taylor Swift's "We Are Never Ever Getting Back Together" down to No. 2 after two weeks in charge. What other moves shake up the Hot 100 and other song charts?

-- Demi Lovato: Just in time for her debut at the judges' table on Fox's "The X Factor" (Sept. 12), Demi Lovato notches her first Mainstream Top 40 No. 1 with "Give Your Heart a Break" (3-1). At 25 weeks, the song completes the longest ascent to No. 1 by a woman in the chart's nearly 20-year history and ties for the longest climb to the top among all artists with Cee Lo Green's "F**k You! (Forget You)" (2010-11). On the Hot 100, "Heart" rises 17-16, reaching a new peak in its 22nd week.

Like Lovato, "Heart" co-writers Billy Steinberg and Josh Alexander each make their first visits to the Mainstream Top 40 summit. However, previous to the launch of the Mainstream Top 40 chart in 1992, Steinberg topped the Billboard Hot 100 with five titles: Madonna's "Like a Virgin" (1984); Cyndi Lauper's "True Colors" (1986); Heart's "Alone" (1987); Whitney Houston's "So Emotional" (1988); and the Bangles' "Eternal Flame" (1989).

"Heart" marks Hollywood Records' third Mainstream Top 40 No. 1, following Miley Cyrus' "Party in the U.S.A." (2009) and Jesse McCartney's "Leavin' " (2008).

-- Usher: As his former No. 10 Hot 100 hit "Scream" slips 30-33, it rises 2-1 on Hot Dance Club Songs. The song marks Usher's first topper on the latter tally as a lead artist. His sole previous trip to the top occurred as a guest (with Lil Wayne) on Enrique Iglesias' "Dirty Dancer" last year.

-- Matchbox Twenty: Ahead of the expected debut of North high atop next week's Billboard 200, "She's So Mean," the set's lead single charges 53-40 with Greatest Gainer/Digital honors on the Hot 100. The song pushes 32-28 on Hot Digital Songs (55,000 downloads sold, up 32%, according to Nielsen SoundScan).

-- OneRepublic: "Feel Again," the first taste of the band's forthcoming third album, arrives as the Hot 100's Hot Shot Debut at No. 61. It launches at No. 22 on Hot Digital Songs (61,000) and No. 24 -- a career-best bow -- on Adult Top 40.

-- Alicia Keys: The pianist extraordinaire earns the top new entry on Hot R&B/Hip-Hop Songs (No. 67), as "Girl on Fire" garnered 2.1 million audience impressions in less than a day, according to Nielsen BDS. The song is the first single from her forthcoming album of the same name, due Nov. 27. "Girl" was released in three versions: its original mix, an "Inferno" remix featuring Nicki Minaj and a stripped-down "Blue Light" version.
