50 Cent's "In Da Cub" is standing its ground on Billboard's singles charts, holding onto No. 1 on the Hot 100, the Hot R&B/Hip-Hop Singles & Tracks chart, and the Hot Rap Tracks tally. Taken from the rapper's former No. 1 Billboard 200 album, "Get Rich or Die Tryin'" (Shady/Interscope), the single has topped the Hot 100 for six weeks, the R&B/hip-hop list for nine weeks, and the rap chart for an impressive 10 weeks.

On the Hot 100, R. Kelly's "Ignition" continues its stay at No. 2, while Sean Paul's "Get Busy" jumps 6-3, thanks to a hefty burst in airplay.

In the same week that its sophomore album, "Meteora," blasts onto The Billboard 200 at No. 1, Linkin Park gains control of both of Billboard's rock airplay charts. The Warner Bros. act's "Somewhere I Belong" knocks Evanescence's "Bring Me To Life" featuring Paul McCoy from the top of Modern Rock Tracks tally, and displaces Godsmack's "Straight Out of Line" from the peak of the Mainstream Rock Tracks chart. Linkin Park previously had a No. 1 cut on the Modern Rock Tracks chart in 2001 with "In the End."

Kid Rock's "Picture" featuring Sheryl Crow/Allison Moorer is the top-selling single in the U.S., according to Nielsen SoundScan, and is No. 1 on Billboard's Hot 100 Singles Sales chart for the 10th week. The track also maintains its No. 4 position on the Hot 100 despite a slight decrease in airplay.

New in the top-10 of the Hot 100 is Snoop Dogg's "Beautiful" featuring Pharrell & Uncle Charlie Wilson, as it hops 12-7, bringing the cut to a new peak position. The track also moves up one to No. 3 on the Hot R&B/Hip-Hop Singles & Tracks chart.

Christina Aguilera's "Fighter" is the Hot 100's top debut, punching its way onto the chart at No. 61. Other notable newcomers include Nelly's "Pimp Juice" at No. 68, Frankie J.'s "Don't Wanna Try" at No. 76, Reina's "No One's Gonna Change You" at No. 96, and Panjabi MC's "Beware of the Boys (Mundian to Back Ke)" featuring Jay-Z.

Country radio continues to bleed patriotism, as Darryl Worley's "Have You Forgotten" holds onto No. 1 on Billboard's Hot Country Singles & Tracks chart for a second-straight week. The pro-war anthem logged more than 6,000 spins at stations monitored by BDS.
