A a small-town girl hailing from Checotah, Okla., Carrie Underwood first came into the spotlight after her 'American Idol' win in 2005, and the now five-time Grammy winner is celebrating 10 years of country music by releasing a two-disc album, 'Greatest Hits: Decade #1.'

She made the big announcement on the 'Today' show on Sept. 26, also revealing details about the corresponding single, 'Something in the Water.' Since then, Underwood has been slowly disclosing other details about the record, including the track listing, the release date and the gorgeous cover. Here's what we know about the singer's upcoming record.

The Title

Underwood's new record is called, fittingly, 'Greatest Hits: Decade #1.'

"I can’t believe it’s been a decade since I auditioned for "American Idol,'" she says. "Looking back at the songs I've released over the years lets me relive my amazing journey. Even better, I get to include new music for the fans."

The Cover

The cover of 'Greatest Hits: Decade #1' is almost as gorgeous as Underwood herself. The photo is shot in black and white, giving it a classic, elegant look, and she's laying on a tufted leather couch, looking glamorous in a beautiful dark gown, her long locks in immaculate curls. It's, in a word, timeless.

The Release Date

Underwood will be releasing the record on Dec. 9 via 19 Recordings / Arista Nashville. It can be physically pre-ordered here, and is also available for digital pre-orders.

The Single

When the 31-year-old announced the album, she also disclosed the lead single, ‘Something in the Water,' which features lyrics that give testament to her Christian faith: "Got joy in my heart, angels on my side / Thank God almighty, I saw the light / Gonna look ahead no turning back / Live everyday giving all that I have / Trust in someone bigger than me / Ever since the day that I believed.”

“It’s really kind of a joyous, uplifting song about changing your life for the better and kind of having that ‘a-ha’ moment, to waking up and your life being different from that moment forward,” Underwood explains.

She's also revealed the inspirational and dance-filled music video for 'Something in the Water,' and she performed the ballad-driven single at the 2014 CMA Awards.

The Songs

Underwood's upcoming album will showcase some of her 18 No. 1 singles spanning her four full-length studio albums, as well as other songs, totaling at 25 tracks. It includes two new songs -- 'Little Toy Guns' (written by Underwood, Chris DeStefano and Hillary Lindsey) and 'Something in the Water' -- plus four songs in never-before-released versions. The latter are writing session renditions of ‘So Small,’ ‘Last Name’ and ‘Mama’s Song,’ as well as a duet of the hymn ‘How Great Thou Art,' featuring Vince Gill, from the from the Academy of Country Music TV special 'ACM Presents: Girls' Night Out' in 2011.

Another New Album is Coming

As if a greatest hits album, new baby boy on the way and recently co-hosting the 2014 CMAs with Brad Paisley isn't enough, Underwood is also working on a follow-up to her platinum-selling 'Blown Away' record, released in 2012. Although she hasn't divulged much information, she says it is a "new version" of herself -- and she's been writing for it.

“I've been writing a lot. It feels really good,” Underwood shares.“It’s just a progression, a different sound without losing myself in it. I’m not taking some crazy musical departure from what I’ve done, but it definitely feels different. It will feel different, look different, sound different.”
