California rockers Incubus have been making music together for more than 15 years — and in all that time, they've never known what it was like to have one of their records debut at the top of the Billboard albums chart. That's about to end.

With close to 165,000 copies of Light Grenades sold, Incubus lay claim to the chart's #1 position during another strong week for album sales overall, according to the latest SoundScan data. While Light Grenades is the band's highest-charting album, it isn't its best-selling debut. Incubus' Morning View bowed at #2 in 2001, selling 266,000 copies its first week in stores, while 2004's A Crow Left of the Murder just missed the mark yet again, finishing as the chart's #2 disc with sales of nearly 332,000.

Jay-Z is at the center of the week's other big chart story. Sales of his latest album, Kingdom Come, slipped a whopping 79 percent its second week in stores. The disc, which topped the previous Billboard albums chart with more than 680,000 copies sold, falls to #6 with 140,000 sales — the largest week-two drop of the rapper's career.

Incubus' Grenades was one of just three new albums to crack this week's top 200, with the other new entries coming from the Clipse — whose oft-delayed Hell Hath No Fury debuts at #14 with more than 78,000 scans — and the Ying Yang Twins, who open at #40 after selling 36,000 copies of Chemically Imbalanced. Total sales of the albums on the latest chart fell substantially — from 7.5 million to 5.3 million, with most albums on the chart experiencing slight declines — from those generated the previous week, which is typically thought of as the first of the holiday shopping season.

The soundtrack to the Disney Channel original series "Hannah Montana" climbs five spots to #2 with 157,000-plus copies sold. Sales of the self-titled debut offering from Daughtry, the band fronted by "American Idol" finalist Chris Daughtry, slipped 49 percent, bumping the disc one spot to #3 with nearly 156,000 scans. Now That's What I Call Music! 23 — a collection of singles from hitmakers including Justin Timberlake, Nelly Furtado and Christina Aguilera — finishes at #4 with 154,000 copies sold, followed at #5 by the Beatles' Cirque du Soleil soundtrack project Love, with 146,000 scans.

For the first time since its release seven weeks ago, Sarah McLachlan's holiday-themed Wintersongs makes the chart's top 10, thanks to a 38 percent sales boost. The album sold more than 116,000 copies, and climbs 15 spots to #7. Akon's Konvicted holds #8 with 110,000 units scanned, while Josh Groban's Awake returns to the top 10 at #9 with 108,000 sales.

Rounding things out at #10 is the third installment in the Now That's What I Call Christmas! compilation series. The two-disc collection — which features classic Yuletide tunes from Nat King Cole, Frank Sinatra, Bing Crosby, and Johnny Cash as well as cuts from contemporary artists including Christina Aguilera, Jessica Simpson, the Pussycat Dolls, and Relient K — sold close to 102,000 copies, making it another first-timer to the top 10; it was originally released eight weeks ago.
