For those keeping score, there are now three albums in the top 10 that feature a cover of Mariah Carey’s 1994 chestnut “All I Want For Christmas Is You,” which she co-wrote with Walter Afanasieff. Both sets by Buble (No. 2) and Bieber (No. 5) boast the track, as does the “Glee” effort at No. 6. Can you hear Carey counting her Christmas cash?
