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

LMFAO leaps to its first No. 1 on the Billboard Hot 100, to be released tomorrow (July 7) on Billboard.biz, as "Party Rock Anthem," featuring Lauren Bennett and GoonRock, lifts 3-1 with Greatest Gainer/Digital honors.

"Party" powers by 22% in digital sales to 258,000 downloads sold, according to Nielsen SoundScan, likewise rising 3-1 on Hot Digital Songs. On Hot 100 Airplay, the track bumps 4-3 with a 13% gain to 115 million in all-format audience, according to Nielsen BDS.

Twosome LMFAO is the first duo or group to top the Hot 100 since Far*East Movement spent the last of three weeks at No. 1 with "Like a G6," featuring Cataracs & Dev, on the Nov. 27, 2010, chart.

The last prior duo to lead the Hot 100? OutKast, which reigned back-to-back with "Hey Ya!" (nine weeks) and "The Way You Move," featuring Sleepy Brown (one), in 2003-04.

LMFAO and OutKast, the latter of which also reigned with "Ms. Jackson" the week of Feb. 17, 2001, are the only duos to command the Hot 100 since R&B pair K-Ci and JoJo spent three weeks at No. 1 with "All My Life" in April 1998.

LMFAO's Hot 100 coronation also brings a musically-rich bloodline to the chart's apex, as the dance/pop/hip-hop duo consists of DJs Redfoo and SkyBlu, aka Stefan Gordy and Skyler Gordy, the son and grandson, respectively, of Motown Records founder Berry Gordy. By reaching No. 1, Stefan claims bragging rights over his older brother (by 11 years), Kennedy. The latter singer - billed as Rockwell - peaked at No. 2 with "Somebody's Watching Me," in 1984.

English singer Bennett and Los Angeles producer GoonRock also each enjoy their first trip to the top of the Hot 100.

"Party" bumps Pitbull's "Give Me Everything," featuring Ne-Yo, AfroJack and Nayer, to No. 2 after it had ascended 2-1 on last week's Hot 100. The song retains its bullet despite its drop in position, as it gains by 2% in airplay to 150 million (holding 2-2 on Hot 100 Airplay) and 2% in download sales to 192,000 (4-3 on Hot Digital Songs).

Adele's former seven-week Hot 100 No. 1 "Rolling in the Deep" dips 2-3, while Katy Perry's "Last Friday Night (T.G.I.F.)" spends a third week at No. 4, claiming the Hot 100's Greatest Gainer/Airplay award for a second consecutive week. On Hot 100 Airplay, the track blasts 11-8 (84 million, up 34%) in its fourth frame, marking the second-fastest climb to the top 10 this year, after Britney Spears' three-week sprint with "Hold It Against Me."

"Friday" cedes the top spot on Hot Digital Songs (1-2) to "Party" after two weeks at No. 1, logging a 9% decrease to 206,000 downloads sold.

The next three songs on the Hot 100 maintain their rankings from last week: Nicki Minaj's "Super Bass" (5-5), Lady Gaga's "The Edge of Glory" (6-6) and Perry's former five-week topper "E.T," featuring Kanye West (7-7).

Lil Wayne lifts 10-8 on the Hot 100 with "How to Love." The song surges 17-13 on Hot 100 Airplay (58 million, up 14%) and, while it rises 10-8 on Hot Digital Songs, it registers a 1% decrease to 128,000 downloads sold.

AS LMFAO returns a duo to the Hot 100's apex, two groups enter the top 10.

OneRepublic's "Good Life" charges 18-9 after frontman Ryan Tedder sang the song with finalist Beverly McClellan on last Wednesday's (June 29) first-season finale of "The Voice." The song, OneRepublic's second Hot 100 top 10, following its No. 2 turn as a featured act on Timbaland's "Apologize" in 2007, bounds 17-12 on Hot Digital Songs (111,000, up 22%) and 18-12 on Hot 100 Airplay (59 million, up 20%).

Hot Chelle Rae likewise reaches the Hot 100's top bracket, as its first chart entry, "Tonight Tonight," jumps 13-10, driven by a No. 9 ranking on Hot Digital Songs (128,000, down 7%) and a 34-26 advance on Hot 100 Airplay (40 million, up 15%).

The Nashville quartet, which includes Nash Overstreet, the brother of now-former "Glee" regular Chord Overstreet and son of Paul Overstreet, who charted nine top 10s on Billboard's Hot Country Songs chart in 1988-91, is the first group to send its maiden Hot 100 entry to the top 10 since Far*East Movement.

(Unlike the Gordy brothers, Nash doesn't best the highest Hot 100 rank of a sibling who previously inhabited the top 10; the "Glee" cast's "Loser Like Me," on which Chord sang, debuted and peaked at No. 6 in April).

All charts, including the Hot 100, Hot Digital Songs and Hot 100 Airplay, will be refreshed tomorrow on Billboard.biz.
