Rihanna‘s reign won’t let up, with her “Rude Boy” at No. 1 for the fifth straight week. Again, to Bruno Mars’ dismay,  B.o.B’s “Nothin’ On You” sits at No. 2. And Train’s  “Hey, Soul Sister” remains at No. 3.

Lady Antebellum’s “Need You Now” and Lady Gaga’s “Telephone” featuring Beyoncé both dropped down two spots this week, now at No. 6 and 7, respectively. Moving on up is Taio Cruz’s “Break Your Heart,” which jumped up two spots to No. 4. Usher, whose “OMG” debuted at No. 14 last week, climbed into the last spot on the top 10. It’s the 15th top 10 cut of his career.

New entries to the top 20 include Jay-Z’s “Young Forever,” at No. 17, Ke$ha‘s “Your Love is My Drug” at No. 19, and Jack Johnson‘s “You and Your Heart,” which debuts at No. 20.

Pop princess Rihanna continues to dance at the top, but there’s plenty of new blood this week. Who do you think will challenge her?
