Mariah Carey notches her 17th No. 1 hit on the Billboard Hot 100 this week as "Don't Forget About Us" ascends one rung to the top of the chart. Carey and Elvis Presley are now tied for second place among artists with the most No. 1 hits in the rock era. Carey also becomes the only artist to post two No. 1 songs on the Hot 100 in 2005.

Chris Brown's "Run It!" falls to No. 2 on the Hot 100 after five weeks at the top but remains the leader on the Pop 100, where the Carey track rockets 8-2. Nelly's "Grillz" featuring Paul Wall, Ali and Gipp flip-flops 4-3 on the Hot 100 with D4L's "Laffy Taffy," while the Pussycat Dolls' "Stickwitu" rises 7-5 and Nickleback's "Photograph" drops 5-6.

Kanye West's "Gold Digger" featuring Jamie Foxx is down 6-7, while Beyonce's "Check on It" featuring Slim Thug bursts into the Hot 100 with an 18-8 climb, giving the former Destiny's Child member her sixth top 10 hit under her own name.

The Hot 100's top tier is rounded out by Kelly Clarkson's "Because of You," which rebounds 10-9 after having previously peaked at No. 7, and Juelz Santana's "There It Go! (The Whistle Song)," which climbs 12-10.

Rising Def Jam artist Ne-Yo has the Hot 100's fastest growing track at radio with "So Sick," which moves 35-26. The chart's top debut is Ludacris and Field Mob's "Georgia" featuring Jamie Foxx at No. 48, which features a sample of Ray Charles' classic "George on My Mind."

The Nelly track takes over the top slot on Billboard's Hot Rap Songs chart, replacing Dem Franchize Boyz' "I Think They Like Me" featuring Jermaine Dupri, Da Brat and Bow Wow. On the Hot Country Songs roundup, Billy Currington's "Must Be Doin' Something Right" leaps 5-1 to end the one-week reign of Dierks Bentley's "Come a Little Closer," which slips to No. 4.

Reggaeton star Daddy Yankee's "Rompe" is the new leader on Billboard's Hot Latin Songs, nudging last week's chart-topper, Christian Castro's "Amor Eterno," down to No. 5. Elsewhere, the Foo Fighters' "DOA" retains the throne on the Modern Rock chart, while Shinedown's "Save Me" remains No. 1 on the Mainstream Rock tally.

Madonna's "Hung Up" is on top of the Hot Dance Singles Sales chart for the fifth week, matching the five-week run of her most recent No. 1 hit, "Love Profusion," in 2004. "Hung Up" is Madonna's 10th consecutive No. 1 song on this chart, her longest string of No. 1 hits in this tally's history.
