We’re well into the swing of the music industry’s all-important fourth quarter now, with major releases arriving in droves nearly every week. Carrie Underwood‘s Play On led the pack this week with a strong 318,000 copies sold, according to Nielsen SoundScan. That was more than enough for a No. 1 debut on the Billboard 200; last week’s winner, Michael Jackson‘s This Is It, dropped off to a still-solid 196,000 for a No. 2 finish.

Andrea Bocelli bowed at No. 3 with 149,000 copies sold of his yuletide collection My Christmas. Glee: The Music, Vol. 1, rounding up many cover tunes from the Fox series that have already seen substantial digital sales, made it to No. 4 with 113,000. No. 5 went to NOW That’s What I Call Music! 32, which sold 102,000 with recent hits from the Black Eyed Peas, Lady Gaga, Jay Sean, and more. (What, no Owl City?) Weezer hit No. 7 with 66,000 copies sold of Raditude — not an awful number in and of itself, but only about half of what their previous album sold in its first week last summer. Ouch. Down at No. 11, Foo Fighters sold 44,000 copies of their Greatest Hits. Slayer brought a World Painted Blood to No. 12 with 41,000.

And that was it for Top 20 debuts this week. Were you surprised to see how high or low any of these albums placed? Are you, like the record-buying public at large, suffering from Weezer Fatigue? (Sorry, Rivers! Hey, I really enjoy the single.) Weigh in below.
