Web Trends: Watch New LMFAO Video "Sexy And I Know It"

LMFAO spends its fourth week atop the Billboard Hot 100, to be released tomorrow (July 28) on Billboard.biz, with "Party Rock Anthem," featuring Lauren Bennett and GoonRock, while high-profile rap duo Bad Meets Evil charges into the top 10 with "Lighters."

"Party" tallies a fourth week at No. 1 on Hot Digital Songs, although it declines by 3% to 209,000 downloads sold, according to Nielsen SoundScan. On Hot 100 Airplay, the track lifts 3-2 with a 5% gain to 143 million in all-format audience, according to Nielsen BDS.

Bad Meets Evil - aka, Eminem and Royce da 5'9" - bookends the Hot 100's top 10 by igniting 17-10 with Greatest Gainer/Digital honors (and besting its No. 16 peak upon its debut five weeks ago). The cut soars 12-5 on Hot Digital Songs, up 56% to 143,000, marking its best sales week to-date. Radio support for the song continues to swell, as it rockets 35-20 on Hot 100 Airplay (47 million, up 35%).

"Lighters" is Eminem's second Hot 100 top 10 this year. He and Skylar Grey guested on Dr. Dre's "I Need a Doctor," which reached No. 4 in March. Eminem has now notched top 10s under three billings, in fact; he sang on D12's No. 6-peaking "My Band" in 2004. (The superstar has logged 14 top 10s as a soloist).

Katy Perry inches closer to a historical Hot 100 No. 1, as "Last Friday Night (T.G.I.F.)" rises 3-2 with Greatest Gainer/Airplay accolades for the fourth time in five weeks. On Hot 100 Airplay, "Friday" lifts 4-3 (129 million, up 12%). The track rebounds 3-2 on Hot Digital Songs, although with a 4% decline to 164,000.

As previously reported <http://www.billboard.com/#/column/chartbeat/weekly-chart-notes-adele-katy-perry-barry-1005250012.story?page=2> , should "Friday" reach the Hot 100 summit, Perry would collect a fifth No. 1 from her album "Teenage Dream," following "California Gurls," featuring Snoop Dogg, the title cut, "Firework" and "E.T.," featuring Kanye West. In the Hot 100's 53-year history, only Michael Jackson's "Bad" (1987-88) has generated five No. 1 singles.

Pitbull's former Hot 100 No. 1 "Give Me Everything," featuring Ne-Yo, Afrojack and Nayer, dips 2-3. The song spends a third week atop Hot 100 Airplay (152 million, down 2%) and slides 6-7 on Hot Digital Songs (127,000, down 7%).

Nicki Minaj's "Super Bass" rises 5-4 on the Hot 100. The song holds at No. 5 on Hot 100 Airplay with a 9% gain to 118 million and ascends 4-3 on Hot Digital Songs, despite a 1% downturn to 154,000.

Adele's former seven-week Hot 100 No. 1 "Rolling in the Deep" slips 4-5, while Lil Wayne holds at No. 6 with "How to Love," which gains in digital sales (139,000, up 2%) and radio airplay (97 million, up 14%).

Hot Chelle Rae's "Tonight Tonight" rises 9-7 on the Hot 100 with gains in download sales (148,000, up 13%) and at radio (58 million, up 14%).
