Rihanna's "Rude Boy" remains stationed at No. 1 on the Billboard Hot 100 for a fifth week, fending off runner-up "Nothin' On You" by B.o.B featuring Bruno Mars (2-2) for yet another frame. "Nothin" takes the chart Airplay Gainer trophy with an increase of 11 million listener impressions. B.o.B also posts a new entry on the list with the No. 67 arrival of "Don't Let Me Fall."
Joining the top 10 party in only its second week on the chart is Usher's "OMG," featuring will.i.am, which motors 14-10. The track is Usher's 15th top 10 and first since he topped the list with "Love in this Club" for three weeks in March 2008. Usher hasn't had a song reach the top 10 this quickly since 1998 when "Nice & Slow" debuted at No. 9 and "My Way" went 13-9 in its second week on the list.
Train's "Hey, Soul Sister" remains stuck at No. 3 for a third week. Moving into the No. 4 slot (6-4) is former No. 1 "Break Your Heart" by Taio Cruz featuring Ludacris. Increased radio play is the cause for Cruz's rebound as the track reaches the top 10 of Radio Songs for the first time (14-9) this week.
