Eminem's "Lose Yourself" leads Billboard's Hot 100 for a 12th-straight week, but B2K's "Bump, Bump, Bump" featuring P. Diddy is making it a tight race. The latter is up 4-2 and gaining spins at radio, while airplay for "Lose Yourself" is slowly starting to dwindle.

"Bump, Bump, Bump" holds at No. 2 on Billboard's Hot R&B/Hip-Hop Singles & Tracks tally, where Aaliyah's "Miss You" is the new No. 1. The late singer's track makes a 5-1 jump to replace Erykah Badu's "Love of My Life (An Ode to Hip-Hop)," which falls to No. 4. "Miss You" is Aaliyah's first posthumous No. 1 single, and third overall.

Back on the Hot 100, Nelly's "Air Force Ones" featuring Kyiuan, Ali & Murphy Lee holds at No. 3. The cut takes over the reigns on Billboard's Hot Rap Tracks tally, ousting Missy "Misdemeanor" Elliott's "Work It" from the top spot. That cut had peaked at No. 2 on the Hot 100, but this week falls to No. 6.

Avril Lavigne scores her third top-10 hit on the Hot 100 as "I'm With You" soars 11-7 thanks to a hefty gain at radio. "Complicated," the lead single from her hit Arista album "Let Go," peaked at No. 2, while its follow-up, "Sk8er Boi," topped out at No. 10.

Justin Timberlake's "Cry Me a River" is the Hot 100's fastest-growing track at radio, and earns a 15-8 burst on this week's chart. This is the 'N Sync member's highest-ranking single as a solo artist, as his "Like I Love You" didn't make it past No. 11. Jennifer Lopez's "All I Have" featuring LL Cool J breaches the top-10 for the first time with a 12-10 jump. Her "Jenny From the Block" featuring Jadakiss & Styles, which in December peaked at No. 3, isn't far behind as it hovers at No. 14 this week.

The Hot 100's fastest-growing track at retail is Kid Rock's "Picture" featuring Sheryl Crow/Allison Moorer, but the cut is unable to gain any ground on the chart, and holds at a respectable No. 24. "Picture" also ends the 11-week rule of Madonna's "Die Another Day" as the top-selling single in the U.S. as it is the ne No. 1 on the Hot 100 Singles Sales Chart.

Rapper 50 Cent continues to make gains in mainstream markets. His "In Da Club" jumps 55-27 this week on the Hot 100, while his "Wanksta" -- from the Shady/Interscope "8 Mile" soundtrack -- scoots 31-29. On the Hot R&B/Hip-Hop Singles & Tracks chart, "In Da Club" bolts 23-7 and "Wanksta" holds at No. 12.

The Hot 100's top debut is Lonestar's "Unusually Unusual" at No. 73. Another country cut is close behind, as Joe Nichols' "Brokenheartsville" parks at No. 74. The only other debut on the Hot 100 is Angie Martinez's "Take You Home" featuring Kelis at No. 95.

Over on Billboard's rock airplay charts the Foo Fighters and 3 Doors Down continue their dominance. The Foos' "All My Life" leads the Mainstream Rock Tracks tally for a 10th-straight week, while 3 Doors Down's "When I'm Gone" maintains its grip on the top of the Modern Rock Tracks chart for a ninth week in a row.
