The Black Eyed Peas hold at No. 1 on the Billboard Hot 100 for a second week with "Imma Be." The track returns to the top of Digital Songs for a second frame after abdicating the lead spot to "We Are The World 25: For Haiti" by Artists for Haiti for the past two weeks.

Young Money moves into the Hot 100 runner-up slot with "BedRock," a new peak for the track. Returning to its prior peak is Lady Antebellum's "Need You Now" which climbs 5-3. It held the same spot three weeks ago.

Ke$ha's "TiK ToK" tumbles 2-4, while Lady Gaga dips 4-5 with "Bad Romance." Train's "Hey, Soul Sister" moves up a spot (7-6), as does Ludacris' "How Low" (8-7).

Rihanna captures her 14th Hot 100 top 10 as "Rude Boy" catapults 23-8, taking dual Digital & Airplay Gainer honors for a second straight week. The last track to take those awards in successive weeks was Beyonce's "Irreplaceable" in late 2006 as it was making its way to No. 1.

Rihanna has now posted the most Hot 100 top 10s by a female artist since the beginning of the last decade. She had been tied with Beyonce (13 top 10s) among women and is now even with Ludacris (14) for second among all artists. Only Jay-Z, with 15 top 10s since 2000, has scored more.

The last two titles in this week's top 10 swap spots with Trey Songz's "Say Aah" moving 10-9 and Jason Derulo's "In My Head" dropping 9-10.

Ludacris appears on the chart's top two debuts. His own "My Chick Bad," featuring Nicki Minaj, opens at No. 46 while he's featured on British newcomer Taio Cruz's "Break Your Heart," which starts at No. 53. It's the first time in the 10 years Ludacris has been charting- encompassing 43 appearances- that he posts concurrent chart debuts.

Kris Allen arrives at No. 63 with his rendition of the Beatles classic "Let It Be." The live recording, performed on the February 25 "American Idol" broadcast, sells 46,000 downloads according to Nielsen SoundScan, with all proceeds going to the Idol Gives Back Foundation, benefitting the relief efforts in Haiti.

Reggae vocalist Matisyahu posts his second Hot 100 appearance as "One Day" opens at No. 90. The song was featured heavily during NBC's coverage of the XXI Winter Olympics and shifts 27,000 downloads. He last appeared on the chart with "King Without A Crown" (No. 28 peak in 2006).

Rounding out this week's eight new debuts are Trey Songz's "Neighbors Know My Name" (No. 88), "Women Lie, Men Lie" by Yo Gotti featuring Lil Wayne (No. 93) and Joe Nichols' "Gimmie That Girl" (No. 98).
