Lady Antebellum‘s “Need You Now” steps back from No. 4 to No. 5 and Train’s “Hey, Soul Sister” from No. 5 to No. 6.

Don’t feel too bad for B.o.B. The rapper’s new single “Airplanes,” featuring Eminem and Hayley Williams is making a run for the top spot, shooting up from No. 9 to No. 7.

Ke$ha’s “Your Love Is My Drug” repeats at No. 8. Jason DeRulo’s “In My Head” falls from No. 7 to No. 9.

Jay-Z‘s “Young Forever” rounds out the top 10, jumping from No. 12 to No. 10. He now leads all rappers with the most to top 10 singles ever. He’s got 17 under his belt. Before “Young,” Jay’s 16 tied him with Ludacris. Luda’s on his heals, though. His “My Chick Bad,” featuring Nicki Minaj is at No. 11 this week.

Drake’s debut single “Over” from his forthcoming debut, Thank Me Later, moves up from No. 16 to No. 14. As does Lady Gaga’s “Alejandro” from No. 20 to No. 16.

Do you think Ludacris is going to catch Jay-Z soon? Happy Usher’s at No. 1 again?
