Miranda Lambert's Crazy Ex-Girlfriend debuts this week at the top of Billboard's country album chart -- just ahead of her significant other, Blake Shelton. But how can you not love someone who has the audacity to choose Pure BS as the title of their new album?

Meanwhile, Sugarland's "Settlin'" tops the trade publication's country singles chart, moving Rascal Flatts' "Stand" to the No. 2 position.

First week sales of Lambert's album totaled more than 52,000 copies to also debut at No. 6 on the Billboard 200. However, she was eclipsed on that all-genre chart by new albums debuted by Michael Buble, Rush and Tori Amos. Shelton's Pure BS landed at No. 8. Lambert's first album, Kerosene, debuted at No. 1 in 2005.

With Lambert and Shelton in first and second place on the list of country albums, Carrie Underwood's Some Hearts endures what will likely be a temporary drop from No. 1 to No. 3. In fact, the new additions to the chart have caused a downward shift all of all titles in the Top 10. In descending order, the other seven CDs are Tim McGraw's Let It Go, Martina McBride's Waking Up Laughing, Taylor Swift self-titled debut, Rascal Flatts' Me and My Gang, Alison Krauss' A Hundred Miles or More: A Collection, Bucky Covington's self-titled release and Larry the Cable Guy's Morning Constitutions.

The only other CD to hit the country chart this week is What I Love About Sunday, a multi-artist inspirational compilation that gets its title from the Craig Morgan hit. Others on the collection include McGraw, Wynonna, Randy Travis, Tracy Lawrence and Billy Ray Cyrus.

One of the tracks worth noting from What I Love About Sunday is Clay Davidson's "Unconditional," which reached No. 3 on the country singles chart in 2000. Davidson, a Virginia native, was off to a strong start on the Virgin Nashville label but somehow got lost in the shuffle when Virgin closed its country division and moved its artists to the Capitol Nashville roster. And that's a shame, but it all happened long before being a redneck became fashionable again.

Sugarland and Rascal Flatts continue to dominate the uppermost region of the country singles chart, but Billy Currington's "Good Directions" shows upward movement by climbing to No. 3. Underwood's recent No. 1, "Wasted," rolls to No. 4 while Toby Keith spends a second week at No. 5 with "High Maintenance Woman." Emerson Drive is also on the upswing with "Moments" rising to No. 6. Alan Jackson's "A Woman's Love" slips to No. 7 as Brad Paisley's "Ticks" digs in at No. 8 for a third week. Also holding steady -- at No. 9 -- is Tracy Lawrence's "Find Out Who Your Friends Are." Dierks Bentley's "Long Trip Alone" rises one notch to No. 10.

Joe Nichols' "Another Side of You" arrives at No. 50 to become this week's highest-charting single. Newcomer Sarah Johns makes a bow at No. 57 with "The One in the Middle."
