Biggest Debuts: The latest installment in the Kidz Bop series—Kidz Bop 13, which has covers of the Shop Boyz, Fergie, and Colbie Caillat, among others—entered the chart at No. 4, selling 49,000 copies. Coming in at No. 8 and selling 37,000 copies was Chris Cagle's My Life's Been A Country Song, and entering the chart at No. 19 was Jim Jones' Harlem's American Gangster, which sold 25,000 copies.

Notable Jumps: Another interesting gainer lurking in the lower reaches of this week's charts: the soundtrack for Once, which was honored with an Oscar on Sunday night and which actually dropped 2% in overall sales. But contrast that dip with the album's 82% gain on the digital-sales chart; its week-to-week digital sales went up by about 5,000 copies, while "Falling Slowly," the track that won Oscar gold, also made a reappearance on the digital-tracks chart at No. 103, selling 14,000 copies and shooting up 359%.

Given that two weeks ago, Herbie Hancock and Amy Winehouse experienced impressive digital gains in the few hours after the Grammys—which were followed by both albums shooting up the big chart thanks to people reaching their brick-and-mortar stores during the week—one could think that the digital-sales chart of the week immediately following a Sunday-night awards ceremony now serves as a sort of leading indicator for sales leaps on the big chart in the week after.

Dropping Off: Let's just say that it was another bad week for the record business, with overall sales dropping 18.5% week-to-week and off 13.1% from this week last year.

Nickelback Award For Inexplicable Durability: That Sara Bareilles—what a cutie! Well, to people who aren't me; they're still buying her album Little Voice in relative droves, and she was the only member of the top 20 to experience a sales increase this week. (She's up 9% to 37,000 sold; that tally propelled her from No. 21 to No. 7.)
