Rihanna maintains her No. 1 standing on the Billboard Hot 100 as "Rude Boy" holds at No. 1 for a second week. The track earns the Airplay Gainer award for a fifth straight frame, the longest streak since Black Eyed Peas had an equal run with "I Gotta Feeling" in July/August 2009.

"Rude Boy" bounces 7-2 on Radio Airplay with 98.3 million listener impressions (up 16.2 million).

Atlanta rapper B.o.B jumps 5-2 on the Hot 100 with "Nothin' on You," featuring Bruno Mars. Lady Gaga and Beyonce dial up the biggest mover within the top 10 as "Telephone" soars 9-3.

After holding the runner-up slot for the past two weeks, Lady Antebellum's "Need You Know" dips 2-4. Also slipping two spots is Taio Cruz's "Break Your Heart" (3-5), which is able to hold on to its No. 1 ranking on Digital Songs for a third week.

The Black Eyed Peas fall back 4-6 with "Imma Be," while Train's "Hey, Soul Sister" dips 6-7, though the title keeps it bullet as it continues to gain in radio airplay.

Rounding out the top 10 are "BedRock" by Young Money featuring Lloyd (7-8), Ke$ha's "TiK ToK" (8-9) and "Baby" by Justin Bieber (12-10).

Bieber's track returns to the top 10 for the first time since it debuted at No. 5 two months ago, posting it best download sum since that debut frame (130,000). Meanwhile, Bieber scores the Billboard Hot 100's Hot Shot Debut for the second time in three weeks as "U Smile" opens at No. 27, selling 83,000 downloads. Two weeks ago, "Never Let You Go" debuted at No. 21 (101,000). The three tracks preview his "My World 2.0" album set to debut atop the Billboard 200 next week.

Last week's Hot Shot Debut, Drake's "Over," earns further accolades as it jumps 35-17 as the Digital Gainer (100,000, up 115%).

Among the other debuts, T.I. debuts at No. 44 with "I'm Back," which serves as his return to the list following his release from prison in December and Maine rapper Spose opens at No. 54 with the modestly titled "I'm Awesome." The song moves 33,000 downloads in its first week of release and also debuts at No. 36 on Pop Songs.

Also debuting are new tracks by Usher (No. 76), Disney's Friends for Change, featuring Joe Jonas and Demi Lovato (No. 84), The-Dream (No. 92), Maxwell (No. 96) and George Strait (No. 100).
