Snoop Dogg is so enjoying his first stint at the top of Billboard's Hot 100 that he has extended it to a second week. The rapper's hit single "Drop It Like It's Hot" featuring Pharrell notches a second week at No. 1 on the tally as it also logs a second week atop Billboard's Hot 100 Airplay list, a fifth on the Hot R&B/Hip-Hop Airplay chart, a sixth on the Hot R&B/Hip-Hop Singles & Tracks roundup and a seventh on the Hot Rap Tracks chart.

Usher and Alicia Keys' former No. 1 duet "My Boo" is No. 2 on the Hot 100 for a second week. The two artists were the top winners at last night's (Dec. 8) Billboard Music Awards (BMA) in Las Vegas, with Usher taking 11 awards including Hot 100 single of the year for "Yeah!" featuring Lil Jon and Ludacris (which spent 12 weeks atop the chart), and Keys earning seven including Hot 100 songwriter of the year.

Usher teamed with Dave Navarro to perform "Bad Girl" from his LaFace/Zomba set "Confessions" -- winner of The Billboard 200 and R&B/hip-hop album of the year awards -- to open the Fox broadcast of the show.

The Hot 100 hosts Mario's "Let Me Love You" and Nelly's "Over and Over" featuring Tim McGraw at No. 3 and No. 4 for a second week, respectively, while Ciara's "1, 2 Step" featuring Missy Elliott climbs up one to No. 5.

Destiny's Child's "Lose My Breath" slips one to No. 6, but the trio shoots 14-10 with "Soldier" featuring T.I. & Lil Wayne, the second single from new album "Destiny Fulfilled" (Sony Urban Music/Columbia).

Lil Jon & the East Side Boyz' "Lovers and Friends" featuring Usher and Ludacris makes a 10-7 move, and is the chart's greatest gainer at radio. Ja Rule's "Wonderful" featuring R. Kelly and Ashanti falls 7-8 and Trick Daddy's "Let's Go" featuring Lil Jon & Twista drops 8-9.

"MTV Ultimate Mash-Ups Presents Jay-Z/Linkin Park: Collision Course" (Warner Bros./Roc-A-Fella) pulled off a No. 1 Billboard 200 debut this week as the set's first single, "Numb/Encore," bolts 65-52 on the Hot 100, and is the chart's fastest-growing track at retail.

Other songs making significant gains this week include Ashanti's "Only U" (35-23), 50 Cent's "Disco Inferno" (54-27) and Jesse McCartney's "Beautiful Soul" (72-58).

At No. 66, Rascal Flatts' "Bless the Broken Road" is the top debut, followed by Kelly Clarkson's "Since U Been Gone" (No. 70), Reba McEntire's "He Gets That From Me" (No. 71) and re-entering the chart, Prince's "Call My Name" (No. 100).

Tim McGraw earns his 21st No. 1 on Billboard's Hot Country Singles & Tracks list with the 2-1 move of "Back When." With a total of 10 weeks atop the chart, McGraw ties Kenny Chesney as the artist with the most weeks this year.

Green Day's "Boulevard of Broken Dreams," which the band performed during last night's BMA broadcast, holds the top spot on the Modern Rock chart for a second week. On the Mainstream Rock Tracks list, Chevelle's "Vitamin R (Leading Us Along)" ends the 10-week reign of Velvet Revolver's "Fall to Pieces," which falls to No. 2.
