Plus: JoJo [ tickets ], Dierks Bentley [ tickets ], more

Sarah McLachlan [ tickets ]
"Wintersong"
(Arista)

The Lilith Fair founder follows 2003's "Afterglow" with the release of her first holiday CD, "Wintersong."

The set was produced by longtime McLachlan collaborator Pierre Marchand, and the track list includes such classic seasonal offerings as "I'll Be Home for Christmas," "O Little Town of Bethlehem," "Silent Night" and "Have Yourself a Merry Little Christmas."

The disc also includes one original composition, "Wintersong," and a cover of John Lennon's "Happy Xmas (War Is Over)."

Vince Gill [ tickets ]
"These Days"
(MCA Nashville)

How much Vince Gill can fans handle? The country superstar will find out when he releases the massive "These Days"--a 4-CD set of 43 new original tunes.

Gill is accompanied on this hugely ambitious endeavor by a suitably large cast of guest stars, including Sheryl Crow, Bonnie Raitt, Diana Krall, Rodney Crowell, Phil Everly, The Del McCoury Band and Emmylou Harris.

Diddy
"Press Play"
(Bad Boy)

Sean "Diddy" Combs [ tickets ] calls in his favors on this album, which features a regular "Who's Who" of the hip-hop and R&B world.

"Press Play" includes performances by such all-stars as Christina Aguilera, Mary J. Blige, Jamie Foxx, Keyshia Cole and Fergie.

JoJo [ tickets ]
"The High Road"
(Blackground)

Teen star JoJo, who released her self-titled debut at the tender age of 12, is back with her sophomore effort, "The High Road." Her first record went platinum on the strength of the singles "Leave (Get Out)" and "Baby It's You."

The 15-year-old crooner, who also starred in the films "Aquamarine" and "RV," already has another hit on her hands with the new album's first single, "Too Little Too Late."

Dierks Bentley [ tickets ]
"Long Trip Alone"
(Capitol)

Having mined platinum with his previous two outings, 2003's self-titled debut and 2005's "Modern Day Drifter," the CMA Male Vocalist of the Year nominee returns with the highly anticipated "Long Trip Alone."

Produced by Brett Beavers, the album features two bona fide hits, "Every Mile a Memory" and "Lot of Leavin' Left To Do." Bentley is supporting the new disc on his Locked and Loaded Tour, which is currently scheduled to last through early December.

Aerosmith
"Devil's Got a New Disguise: The Very Best Of Aerosmith"
(Columbia)

The classic rockers deliver yet another greatest hits package, "Devil's Got a New Disguise." The main selling point of this set, at least for those who already own copies of the band's other best-of collections, is the inclusion of two new songs, "Sedonna Sunrise" and the title track.
