Music Photos of the Year 2012
September: Oppen Britney style! PSY, Britney Spears and Ellen perform "Gangnam Style" on "The Ellen DeGeneres Show."

The Korean rapper/singer debuts the buzzworthy 'Gangnam Style' at No. 64. Is an explosion at pop radio up next for the song (and dance)?

'FIRE' POWER: Psy isn't the only artist enjoying VMAs-fueled chart action. Following Alicia Keys and Nicki Minaj's performance of "Girl on Fire" - with a cameo from Olympic gold medalist Gabby Douglas - on MTV's awards/live performance fest, the song vaults onto the Hot 100 at No. 37.

Keys' start is her second-best start among 24 entries dating to her 2001 arrival. She launched at a higher rank only as a duet partner with Usher on "My Boo," which began at No. 29 the week of Sept. 11, 2004. "Girl" soars onto Digital Songs at No. 12 (92,000 downloads sold).

On R&B/Hip-Hop Songs, "Girl" jumps 67-50 (3.7 million in audience, up 73%, according to BDS). The cut is the first single from Keys' forthcoming album of the same name, due Nov. 27.

(ALMOST) FIT FOR A KING: Lil Wayne's "No Worries," featuring Detail, bows at No. 96 on the Hot 100. Now with 107 entries, Lil Wayne moves within one of tying Elvis Presley for the most visits among men in the chart's 54-year history.

Among all acts, Presley and Weezy rank behind only the "Glee" cast, which has charted 203 titles on the Hot 100 since its 2009 arrival. The troupe could return to the chart next week with song's from last night's (Sept. 13) fourth season premiere of the Fox TV series.

'DANCE' CHARTS: Recent birthday girl Beyonce (who turned 31 on Sept. 4) charts a seventh single on the Hot 100 from her album "4," as "Dance for You" shimmies in at No. 100. Can the song become the first Hot 100 top 10 from the R&B-focused set? Of the first six such Hot 100 hits, "Best Thing I Never Had" rose the highest, reaching No. 16 the week of Aug. 13, 2011.

On R&B/Hip-Hop Songs, "Dance for You" pushes 16-13; if it can climb three more rungs, it would become the fourth top 10 on the tally from "4," following "Best" (No. 4), "Party" (No. 2) and "Love on Top" (seven weeks at No. 1).

AS 'NORTH' AS POSSIBLE: Who knew that Matchbox Twenty had so much in common with ... New Edition?

As previously reported, Matchbox Twenty scores its first Billboard 200 No. 1, as "North," the rock band's first full-length studio set since 2002, arrives at the chart's northernmost position. The group had previously peaked as high as No. 3 with its second album, "Mad Season," in 2000.

While "North" marks Matchbox Twenty's first Billboard 200 No. 1, it's not lead singer Rob Thomas' first leading album. The group's frontman ruled with his solo debut," ...Something to Be," which entered the Billboard 200 at No. 1 the week of May 7, 2005.

Most commonly, solo singers lead the chart only after the bands in which they've made their marks have reigned. I.e., three of the Beatles topped the Billboard 200 after the Fab Four had sent 13 titles to No. 1 while the band was active between 1964 and 1970. (Ringo Starr rose as high as No. 2 with 1973's "Ringo.")

How rare is it for a group to notch its first No. 1 after a member has led solo? In the chart's 56-year history, it's happened only once before. R&B crooners New Edition earned their first Billboard 200 No. 1, "Home Again," in 1996 after Bobby Brown had led with "Don't Be Cruel" in 1989. In its hit-making mid-'80s heyday, New Edition had risen as high as No. 6 on the survey with its self-titled 1985 set.

Perhaps the two bands and their successful solo singers aren't so different after all.

Both vocalists are named Robert.

New Edition's 1988 album was titled "Heartbreak," while Thomas reached No. 3 on Adult Pop Songs in 2005 with "This Is How a Heart Breaks."

And, while Brown requested that the object of his affection not be cruel, Matchbox Twenty is similarly complaining. The group's "She's So Mean" bullets at No. 8 on Adult Pop Songs for a second week.
