50 Cent's "In Da Club" maintains its lead on Billboard's Hot 100 for a second-straight week, once again besting Jennifer Lopez's "All I Have" featuring LL Cool J. Additionally, "In Da Club" hasn't loosened its grip on urban markets, as it tops Billboard's Hot R&B/Hip-Hop Singles & Tracks chart for a fifth-straight week and Billboard's Hot Rap Tracks tally for a sixth in a row.

While there have been few changes at the top of the Hot 100 of late, R. Kelly's "Ignition" is starting to shake things up. The track jumps 12-6, and is the chart's fastest-growing track at radio. It also scoots up one to No. 2 on the Hot R&B/Hip-Hop Singles & Tracks survey.

If it weren't for a major spike in airplay for Kelly's "Ignition," the Dixie Chicks might have moved up the Hot 100. Instead, the trio holds at No. 7 with its cover of Fleetwood Mac's "Landslide," but it's notable that it is the chart's fastest-growing track at retail. That song has already been a hit on Billboard's Hot Country Singles & Tracks chart, where it previously reached No. 2. Currently, "Travelin' Soldier" is the Chicks' latest there, where it holds at No. 2 this week behind Gary Allan's "Man to Man," the tally's new No. 1.

Linkin Park crashes onto the Hot 100, arriving at a No. 47 with "Somewhere I Belong." The track is the first single from its forthcoming album "Meteora," due March 25 from Warner Bros. "Somewhere I Belong" is the highest debuting airplay-only rock cut since Creed's "My Sacrifice" entered at No. 50 in 2001.

"Somewhere I Belong" also arrives at No. 2 on Billboard's Modern Rock Tracks tally, where the Red Hot Chili Peppers' "Can't Stop" is No. 1 for the second-straight week. On Billboard's Mainstream Rock Tracks tally, "Somewhere I Belong" enters at No. 5, but "When I'm Gone" from 3 Doors Down rules the for the 16th-straight week.

The Modern Rock Tracks chart is also home to an unlikely entry from a veteran country artist. Johnny Cash's version of Nine Inch Nails' "Hurt" debuts this week at No. 34 on the tally, marking his first-ever entry there. The track debuted last week on the Hot Country Singles & Tracks chart at No. 56, but falls off the 60-postion chart this week.

Back on the Hot 100, other notable newcomers are Darryl Worley's "Have You Forgotten" at No. 50, Evanescence's "Bring Me To Life" featuring Paul McCoy at No. 64, Martina McBride's "Concrete Angel" at No. 65, Keith Urban's "Raining on Sunday" at No. 69, Toby Keith's "Rock You Baby" at No. 72, and the Roots' "Break You Off" featuring Musiq at No. 99.
