Katy Perry's 'Firework' Stays Atop Hot 100, Lil Wayne Cracks Top 10

Katy Perry's "Firework" continues to light up the Hot 100 at No. 1, leading the chart for a third consecutive week and continuing its climb up the Radio Songs chart, where it takes the Airplay Gainer tag with a 6-3 move on the airplay list (119.3 million, up 20%, according to Nielsen BDS). Downloads, however, decline for a third consecutive frame, as "Firework" falls out of the top spot of Digital Songs, dropping to No. 2 with 192,000 (down 5%), according to Nielsen SoundScan.

One explosive title makes way for another atop Digital Songs, as Bruno Mars' "Grenade" takes out "Firework," selling 212,000 downloads (up 14%). The title is Mars' third to lead Digital Songs, following B.o.B's "Nothin' On You," on which he was featured, and "Just the Way You Are." On the Hot 100, "Grenade" gravitates to No. 2 from No. 3 and is in prime position to take over the No. 1 slot next week. "Just the Way You Are," meanwhile, remains in the Hot 100 top 10 for a 15th week, moving 7-6.

Rihanna likewise occupies two slots in the Hot 100 top 10, with her former No. 1s "What's My Name?" featuring Drake (2-3) and "Only Girl (In the World)" (6-7). The former track replaces the latter at No. 1 on Radio Songs, marking the first time that an artist has swapped titles atop that list since T.I. posted back-to-back chart-toppers with "Whatever You Like" and "Live Your Life" (which coincidentally featured Rihanna). T.I.'s two toppers inked consecutive eight-week reigns on Radio Songs between Oct. 4, 2008, and Jan. 17, 2009.

Two other former chart-toppers round out the top five, as P!nk's "Raise Your Glass" holds steady at No. 4 and Ke$ha's "We R Who We R" remains at No. 5. The Black Eyed Peas stay stationary at No. 8 with "The Time (Dirty Bit)," and Nelly drops one slot to No. 10 with "Just a Dream."

Lil Wayne debuts in the top 10 for the second time as a lead artist, as "6 Foot 7 Foot" stomps in at No. 9, selling 166,000 downloads in its first week of release. The title also opens at No. 3 on Digital Songs. Lil Wayne recently started at No. 6 in September with "Right Above It," which opened at No. 1 on Digital Songs with 225,000. Weezy performed "6 Foot 7 Foot," the purported first single from the upcoming "Tha Carter IV," on the Dec. 18 episode of "Saturday Night Live."

Diddy-Dirty Money's "Coming Home" grabs Digital Gainer honors on the Hot 100 for a second straight week and motors 24-19. The track shifts 93,000 downloads (up 42%) and leaps 17-12 on Digital Songs, while increasing its audience by 30% as it rises 64-51 on Radio Songs. The track is from the act's top 10 debuting album, "Last Train to Paris."

Taio Cruz debuts at No. 80 on the Hot 100 with "Higher," featuring Travie McCoy. The song is climbing the Pop Songs list, jumping 33-26 in its second week. Among the Hot 100's other new entries are Nicki Minaj with "Moment 4 Life" (No. 82) featuring Drake, "F**kin' Perfect" by P!nk (No. 86), and Fabolous with "You Be Killin Em" (No. 94).

R. Kelly returns to the list for only the second time since 2007, as "When a Woman Loves" debuts at No. 93. He was last on the list when "Number One" peaked at No. 59 in November 2009.

Mariah Carey charts her second-ever seasonal track on the Hot 100, as "Oh Santa!" opens at No. 100. Carey's 1994 holiday staple "All I Want for Christmas Is You," which Billboard ranked as the most recent season's No. 1 Holiday Song, spent one week on the Hot 100 and peaked at No. 83, but not until 2000. The title was solely available for many years as an album track from her "Merry Christmas" set, which prevented it from charting on the Hot 100. Up until December 1998, a song required a physical single counterpart in order to be eligible for inclusion on the Hot 100.

For the past several years, the sole limitation for holiday songs on the Hot 100 is that they must have been released during the current holiday season. Any songs that charted on a Billboard list or appeared on an album released in a prior year are not eligible.
