Beyonce's First Tweet Causes Social Storm
Beyonce's First Tweet Causes Social Storm

As if nabbing her first No. 1 on Adult R&B last week wasn't enough for Beyoncé, earning the No. 1 spot on the overall R&B/Hip-Hop Songs chart is certainly just right.

"Love on Top," the song that will always remind us of Bey's pregnancy announcement on the MTV Video Music Awards, creeps up to the top (2-1), breaking Drake's five-week stay at the peak with two titles: "The Motto" (now No. 2) and "Make Me Proud," featuring Nicki Minaj (4-5).

Beyoncé banks her sixth solo No. 1 on R&B/Hip-Hop Songs with "Love on Top" (34 million audience impressions, up 14%, according to Nielsen BDS). The last time Beyoncé charted a No. 1 title was in 2008 with "Single Ladies (Put a Ring on It)." With the addition of four No. 1s from her Destiny's Child days, she proudly holds 10 toppers to her name.

As radio promotion executives at RCA work the phones with programmers in hopes of a No. 1 next week, Chris Brown's "Strip," featuring Kevin McCall, rises 5-3. it's Brown's first top three hit since "Look At Me Now," featuring Lil Wayne and Busta Rhymes, planted its feet on the No. 1 plank for eight weeks beginning almost a year ago.

Wale's former No. 1 "Lotus Flower Bomb," featuring Miguel, continues its decent, buckling down 3-4.

Holding tight on the R&B/Hip-Hop Songs ladder, Tyga's "Rack City" stays unchanging, remaining at its No. 6 peak so far for a second week. Read on for details on Tyga's No. 1 launch on R&B/Hip-Hop Albums.

Young Jeezy's "I Do," featuring Jay-Z and Andre 3000, keeps a stone cold grip on the No. 7 spot, while Melanie Fiona is the breakthrough artist of the top 10, as "4 AM," the first single from her sophomore album "The MF Life" (due March 20), rises 11-8 in its 27th week. "4 AM" is her first top 10 since "It Kills Me," the song that put her on the commercial map and became her first No. 1, entered the top 10 in December 2009.

Rounding out the top 10, Trey Songz lifts 10-9 with "Sex Ain't Better Than Love," which swaps spots with J. Cole's "Can't Get Enough," featuring Songz.

An Open Letter to Rihanna | An Open Letter to Chris Brown

HONORABLE MENTION: "Birthday Cake," Rihanna's overtly sexual tune featuring her ex-boyfriend Chris Brown, rockets 71-20 on R&B/Hip-Hop Songs with Greatest Gainer/Airplay credit (11 million in audience, up 481%). The last song led by a woman to make a bigger leap into the top 20 was Mariah Carey's "Touch My Body," which flew 58 rungs (78-20) four years ago this week (on its way to a No. 2 peak).

NO ONE CATCHES TYGA: At the R&B/Hip-Hop Albums camp, surprise! Drake no longer dominates. For the first time since its debut, Drake's "Take Care" (1-3) has been pushed out of its comfort zone in the top two (10 weeks at No. 1, four at No. 2) due to two new starts.

Tyga debuts his sophomore effort "Careless World: Rise of the Last King" with 61,000 copies sold, according to Nielsen SoundScan. (Yes, it is his second album, although it might feel more like freshman year when it comes to Tyga's enrollment at Young Money university. "Careless" is the rapper's first album on Cash Money/Universal Republic). So far, four cuts from the album have charted on R&B/Hip-Hop Songs: "Far Away" (No. 93 peak), "Still Got It" (No. 70), "Faded" (up 97-71 this week) and the brightest star of them all, "Rack City" (see above).

Drake's bunkmate who called shotgun for the top bed is the new alternative hip-hop duo from Philadelphia Chiddy Bang, comprised of college buddies Chidera "Chiddy" Anamege and Noah "Xaphoon Jones" Beresin. The pair's first studio album "Breakfast" begins at No. 2 with 31,000.

Rihanna's "Talk That Talk" slips 2-4, while Young Jeezy's "TM: 103: Hustlerz Ambition" slides 3-5. While it's the latter album's lowest rank so far, it tallies a 10th week in the top five - its entire chart run - dating to its debut at No. 1 the week of Jan. 7.
