Two very different albums -- one bluegrass, one redneck -- enter the Billboard country chart in the Top 10 this week. Alison Krauss & Union Station's Lonely Runs Both Ways arrives at No. 6, selling 70,000 copies in its first week. At No. 10, four down-home funnymen (Jeff Foxworthy, Bill Engvall, Larry the Cable Guy and Ron White) reunite for the Blue Collar Comedy Tour Rides Again soundtrack.

Meanwhile, Shania Twain holds her No. 1 grip with her Greatest Hits, followed by Toby Keith's Greatest Hits 2 at No. 2. Weekly sales for Tim McGraw's Live Like You Were Dying nearly doubled following his NBC-TV special to push it to No. 3. George Strait's 50 Number Ones and Gretchen Wilson's Here for the Party land at No. 4 and No. 5, respectively. Rascal Flatts' Feels Like Today slips a spot to No. 7, just ahead of Big & Rich's Horse of a Different Color at No. 8 and Kenny Chesney's When the Sun Goes Down at No. 9.

Larry the Cable Guy's A Very Larry Christmas remains the top-selling country holiday CD but falls to No. 14 in its second week of release. Bolstered by a symphony tour, LeAnn Rimes' What a Wonderful World wraps up the No. 18 slot. Joe Nichols' A Traditional Christmas comes in at No. 59. Thomas Kincade Country Christmas -- with music from Dolly Parton, Eddy Arnold and Alabama, among several others -- debuts at No. 72.

On the singles chart, Gary Allan holds the No. 1 spot for the second week, with "Nothing On but the Radio." McGraw's "Back When" jumps to No. 2, followed by Chesney's "The Woman With You," Blake Shelton's "Some Beach" and Lonestar's "Mr. Mom" in third through fifth place, respectively.

The first single from his new album is expected early next year, but for now, Dierks Bentley continues to ascend the chart with "How Am I Doin'" moving to No. 6. Darryl Worley's "Awful, Beautiful Life" lands at No. 7, trailed by Twain and Billy Currington's "Party for Two" at No. 8 and Alan Jackson's "Monday Morning Church" at No. 9. Rimes' "Nothin' 'Bout Love Makes Sense" rounds out the Top 10, marking her first appearance there since "I Need You" in late 2000.

The high-energy guys in Sawyer Brown rejoice in their No. 55 debut of "Mission Temple Fireworks Stand" as Nichols exclaims "Let It Snow! Let It Snow! Let It Snow!" at No. 57. New artist Keni Thomas bows at No. 59 with "Not Me," featuring Vince Gill and Emmylou Harris.
