Usher maintains his perch atop the Billboard Hot 100 for a fourth non-consecutive week with his monster smash "OMG," featuring will.i.am. The track moves 2-1 on the Radio Songs chart (139.5 million listener impressions), extending his lead among male artists for the most No. 1s on that 20-year old Nielsen BDS-based list with his seventh chart-topper. Only Mariah Carey, with 11, has earned more. On a less positive note, "OMG" drops from the No. 1 slot on Digital Songs (1-3) as sales decline by 4% to 227,000, according to Nielsen SoundScan.
Moving back to No. 1 on Digital Songs is Katy Perry's "California Gurls," featuring Snoop Dogg (3-1) with a 16% gain to 269,000. The title is the first track to debut at No. 1 on Digital Songs, relinquish the top spot the following week and subsequently return since Beyonce's "If I Were a Boy" in November 2008. Meanwhile "Gurls" surges 15-10 on the Radio Songs tally in its third week on the list, the fastest climb into that chart's top 10 since T.I. also needed three weeks with "Live Your Life" in October 2008. On the Hot 100, the track increases a notch to the No. 2 spot where it debuted two weeks ago
For the second week in a row a title is pushed down 2-3 on the Hot 100 while earning the Airplay Gainer award. Last week it was Perry's "California Gurls." This week B.o.B's "Airplanes," featuring Hayley Williams, holds the distinction. "Airplanes" improves by 19 million listener impressions to 96.7 million, jumping 8-4 on Radio Songs, while holding at No. 2 on Digital Songs with 235,000 (up 1.5%). Meanwhile, B.o.B's former No. 1 "Nothin' On You" slips 5-7.
