Making way for Usher's chart champ is B.o.B's "Nothin' on You" which falls to No. 2 after two weeks on top. The Atlanta rapper's new single "Airplanes," featuring Eminem and Hayley Williams, jumps 9-7 on the Hot 100 and arrives on Radio Songs at No. 41, the highest debut on that chart since Usher's "Love In This Club" opened at No. 38 in the May 10, 2008, issue. B.o.B also debuts on the Hot 100 with "Magic," featuring Rivers Cuomo of Weezer, at No. 83.
Rihanna's "Rude Boy" slips a spot to No. 3, as does Taio Cruz's "Break Your Heart" (3-4), "Need You Now" by Lady Antebellum (4-5) and Train's "Hey, Soul Sister" (5-6).
Ke$ha's "Your Love Is My Drug" holds at No. 8, ahead of Jason DeRulo's "In My Head" which falls 7-9.
Jay-Z once again takes the lead for most top 10s by a rapper on the Hot 100 as "Young Forever" skips 12-10, his 17th title to reach the upper tier. Jay-Z had been tied with Ludacris for that accolade as the two have been jockeying for the lead for the past couple of years. Jay-Z may soon have to share the mark yet again, as Ludacris holds at No. 11 with "My Chick Bad," featuring Nicki Minaj.
The Glee Cast places five new entries on the Hot 100, led by "One Less Bell to Answer/A House Is Not A Home," which is the Hot Shot Debut at No. 53. It's the most titles the troupe has debuted with in a single week, having previously placed four tracks on four occasions, including each of the last two weeks.
Notable debuts among the 13 new entries this week are the Black Eyed Peas' "Rock That Body" (No. 62) and Shakira's "Gypsy" (No. 65). The Peas track is the fifth title to chart from their album "The E.N.D.," the most they've ever placed on the list from one set. Shakira performed her new track on both "The Ellen DeGeneres Show" and "American Idol," prompting a 313% digital spike to 30,000 downloads.
