374,000: Number of copies of Justin Bieber's new album "Believe" that were sold in the first week of release. That number gives the CD the best debut of the year, knocking off Madonna's "MDNA" which sold 359,000. However, the Biebs didn't hit the mark for best week of sales of year -- that honor falls to Adele, who's "21" sold 730,000 copies after the Grammy triumph. This is Bieber's fourth No. 1 album.
