Carrie Underwood has another new award to add to her trophy case. The new mom has topped the RIAA's Digital Singles Ranking for country artists.

Underwood has sold a total of 28 million digital units from 20 songs -- a number that also makes her one of the Top 5 female artists, among all genres, in the history of the RIAA's Digital Singles program. She joins the ranks of fellow women such as Rihanna and Katy Perry.

The "Something in the Water" singer's digital sales numbers are thanks in part to 4.5 million sales of her recent Greatest Hits: Decade #1 album, which includes her current gold-selling digital single, "Little Toy Guns," along with her multi-platinum hit, "Before He Cheats," which has sold more than 5 million copies to date. Underwood is one of only five country artists to earn more than 5 million in sales from a digital single.

The former American Idol winner has clearly found success with her music, but the Oklahoma native says that she will branch out into new territory for her upcoming album.

“There’s definitely a different sound that’s coming together,” Underwood says. “I want everything to have its own space and look different, sound different, feel different. So I’ve been working with another producer, as well as with Mark Bright, who I’m always gonna love, but getting things a little different, and it’s been fun.

“I feel things have a different sort of twang to them, kind of a rock twang,” she adds. “So there should be some things that [fans] hopefully have liked about the music we’ve done, but also a little growth, a little bit of shift, so still things they’ve liked but new things to see, hear and feel.”

All of Underwood's albums are available for download on iTunes.
