Bruno Mars stays at #1 with a 13% bump over the previous week, but Rihanna slips two slots to #4, overtaken by Taylor Swift(+29%) and (we can’t believe we’re typing this) The Lumineers, continuing their improbable upward climb. Ho Ho “Ho Hey” indeed. Otherwise, the Top 10 went through the typical reshuffling, the lone newcomers soon-to-be Voice winnerCassadee Pope with in-show her performance of Keith Urban’s “Stupid Boy,” and another indie act with a feel-good story, this one from Seattle hip-hop mavericksMacklemore & Ryan Lewis.

1. Bruno Mars, “Locked Out of Heaven” – 222k
2. Taylor Swift, “I Knew You Were Trouble” – 167k
3. The Lumineers, “Ho Hey” – 131k
4. Rihanna, “Diamonds” – 121k
5. will.i.am f/Britney Spears, “Scream & Shout” – 120k
6. Cassadee Pope, “Stupid Boy” – 117k
7. Justin Bieber f/Nicki Minaj, “Beauty and a Beat” – 108k
8. Macklemore & Ryan Lewis, “Thrift Shop” – 102k
9. PSY, “Gangnam Style” – 123k
10. Ke$ha, “Die Young” – 94k

All three Voice finalists did decent biz, as Terry McDermott’s cover of “Let It Be” moved 66k units, putting it at #18, and Nicholas David’s “You Are So Beautiful” sold 40k, landing at #38. All three will likely do even better on next week’s chart, which will reflect the highly rated final two shows. For the record, the week’s best-selling Xmas single once again was Mariah Carey’s latter-day standard “All I Want for Christmas Is You,” with another 65k, bringing the life-of-record total to 2.375 million, as Mariah finds herself on both ends of the “Give the Gift of Music” transaction.
