Usher's "Love in This Club" featuring Young Jeezy begins a third week at No. 1 on the Billboard Hot 100 amid a static top 4 that includes Chris Brown's "With You" (No. 2), Flo Rida's "Low" featuring T-Pain (No. 3) and Sara Bareilles' "Love Song" (No. 4).

Also unchanged from last week are Rihanna's "Don't Stop the Music" (No. 5), Jordin Sparks' "No Air" featuring Chris Brown (No. 6) and Ray J and Yung Berg's "Sexy Can I" (No. 7), the latter of which is the chart's fastest growing track at radio.

U.K. phenom Leona Lewis has her first top 10 hit on the Hot 100 this week as "Bleeding Love" zooms 21-8. Digital sales of the former U.K. No. 1 single more than doubled to 120,000.

Timbaland's "Apologize" featuring OneRepublic slides 8-9, while Lupe Fiasco's "Superstar" featuring Matthew Santos holds at No. 10 to round out the top tier.

Rapper Lil Mama's "Shawty Get Loose" makes the biggest jump on the Hot 100 this year with a 92-19 explosion. The track, which features Chris Brown and T-Pain, sold 72,000 downloads this week, good enough for a No. 9 debut on Hot Digital Songs.

The week's top debut comes from Danity Kane's "Damaged" at No. 64 after selling 31,000 downloads. The girl group's second Bad Boy album, "Welcome to the Dollhouse," is in contention to debut at No. 1 next week on The Billboard 200.

On Hot R&B/Hip-Hop Songs, Keyshia Cole's "I Remember" is No. 1 for a sixth week. Lil Wayne has the top debut on the tally with "Lollipop" at No. 56, the second best debut of his career as a lead artist.

Alan Jackson scores his 23rd No. 1 hit on Hot Country Songs with "Small Town Southern Man," which moves up from No. 2. Carrie Underwood, whose "All-American Girl," is unseated by Jackson, has some consolation, as her "Last Name" is the top debut on the chart at No. 46.

Foo Fighters' "Long Road To Ruin" is No. 1 on Billboard's Modern Rock chart for a fifth week, while Puddle Of Mudd's "Psycho" leads Mainstream Rock for a sixth.
