Chris Mann, the pop-opera singer from The Voice, released his debut album on October 30. I can't find any sales numbers for it, which probably means it's DOA.
Scotty McCreery's Christmas album, which was released on October 16, sold 50K last week, putting his total at around 165K.
** Update 12/05/12: HDD shows Phillip getting another 78K for his second week, bringing his total to around 250K. Scotty got another 40K, bringing his total to around 205K.
