Jennifer Lopez's "All I Have" featuring LL Cool J is the new No. 1 on Billboard's Hot 100, knocking B2K's "Bump, Bump, Bump" featuring P. Diddy from the top of after only one week. "All I Have," the Hot 100's fastest-growing track at radio, bolts 5-1 to give Lopez her fourth No. 1 on the chart, and earns LL Cool J his first in his long career.

"Bump, Bump, Bump" doesn't fall far, landing at No. 2. The cut displaces Christina Aguilera's "Beautiful" to No. 3, while Avril Lavigne's "I'm With You" holds at No. 4. Ja Rule's "Mesmerize" earns an 8-5 boost this week, making it the only cut new to the top-5, and mirroring its position on Billboard's Hot R&B/Hip-Hop Singles & Tracks chart.

R. Kelly may be suffering from a new round of child pornography allegations, but his single "Ignition" isn't showing any side effects. The cut is the Hot 100's fastest-growing track at retail, earning it a 17-12 boost. While it doesn't replace Kid Rock's "Picture" featuring Allison Moorer/Sheryl Crow as the country's top-selling single, "Ignition" has a higher chart position than "Picture" (No. 16) due to more radio play.

Elsewhere, Tyrese's "How You Gonna Act Like That" moves 45-31, and in only its second-week on the Hot 100, Eminem's "Superman" soars 55-35. The Hot 100's top debut is Lil' Kim's "The Jump Off" featuring Mr. Cheeks at No. 66. The cut has been making its way up the Hot R&B/Hip-Hop Singles & Tracks chart, and this week cruises 42-26.

Other notable entries on the Hot 100 include the Red Hot Chili Peppers' "Can't Stop" at No. 68, Snoop Dogg's "Beautiful" featuring Pharrell & Uncle Charlie Wilson at No. 69, Alan Jackson's "That'd Be Alright" at No. 74, and DMX's "X Gon' Give It to Ya" at No. 93.

Aaliyah's "Miss You" has control of the Hot R&B/Hip-Hop Singles & Tracks chart for a third-straight week. But 50 Cent's "In Da Club" moves 4-2 and is continuing to gain at radio, and will likely make it a tight race next week. "In Da Club" is No. 1 on Billboard Hot Rap Tracks tally.

Mark Willis' "19 Somethin'" continues its reign on Billboard's Hot Country Singles & Tracks roundup for a fifth-straight week, leading Blake Shelton's "The Baby," which spends a second week at No. 2.

On Billboard's Modern Rock Tracks tally, Queens Of The Stone Age earns its first-ever No. 1 with "No One Knows," replacing Saliva's "Always" at the top spot. There's no change, however, on the Mainstream Rock Tracks chart, where 3 Doors Down's "When I'm Gone" maintains its lead for an 11th-straight week.
