Does performing on the Grammy Awards show one's boost record sales? Oh, yeah. Just ask Lady Antebellum and Miranda Lambert, both of whom had major spots on the Feb. 13 broadcast. Add to that the fact that Lady A spent almost as much time onstage accepting awards -- five in all -- as it did singing and you've got massive prime-time exposure.

The results: Lady A's Need You Now sold 85,243 copies the week following the show, according to Nielsen SoundScan -- compared to 27,921 units the week before, enough to propel the album back to the No. 1 slot on Billboard's country chart.

Similarly, Lambert's Revolution sold 21,215 copies last week, over 7,000 more than in the previous week. In the process, Revolution rebounded from No. 9 to No. 5.

Lambert's beau, Blake Shelton, who gave her such a courtly introduction on the awards show, has his own triumph to grin about. His single, "Who Are You When I'm Not Looking," has moved up to become this week's top country song.

This week's highest debuting album is Hayes Carll's cryptically-titled KMAG YOYO (& Other American Stories), which rolls in at No. 12. There are two other newcomers: George Jones' Hits (No. 39) and the Lacs' Country Boy's Paradise (No. 52).

There are two re-entries: Gretchen Wilson's I Got Your Country Right Here (back at No. 51) and Lady A's iTunes Sessions EP (No. 73).

Eric Church's "Homeboy" is the top-ranking of the week's four new songs to chart, bowing in at No. 48, followed by the Eli Young Band's "Crazy Girl" (No. 51), Toby Keith's "Somewhere Else" (No. 57) and Frankie Ballard's "A Buncha Girls" (No. 59).

The No. 2, No. 3 and No. 4 albums, in that order, are Taylor Swift's Speak Now, Jason Aldean's My Kinda Party and the Zac Brown Band's You Get What You Give.

Trailing Shelton in the Top 5 songs cluster are Aldean and Kelly Clarkson's "Don't You Wanna Stay" (which takes a mighty leap from No. 6), Brad Paisley's "This Is Country Music," Luke Bryan's "Someone Else Calling You Baby" (last week's No. 1) and Swift's "Back to December."

One more thing on the Grammys and sales. Esperanza Spalding, who beat out Justin Bieber, among others, to win the best new artist Grammy, saw sales of her Chamber Music Society CD rocket from 3,105 copies pre-Grammy week to 17,877 post-Grammy.

Weep not for the Bieber, though. His Never Say Never -- Remixes is this week's best-selling album in America, debuting at No. 1 on the Billboard 200 all-genre chart with a total of 161,272 units passing across the scanners.

Ah, the sweet sounds of commerce!
