Oprah, Music Biz Savior?

Is the talk show queen/media mogul going to do for music what her book club seal of approval has done for writers over the years?
Well, in the upcoming weeks she'll be, um, booking the likes of Whitney Houston, Mariah Carey, Black Eyed Peas, Jennifer Hudson, James Taylor, and Rascal Flatts on her show.

Will stores stock up on these artists' most recent titles in anticipation of monster sales? Will they actually sell in any significant numbers due to the Oprah push? Stay tuned. Or not.
