At 430,000, "Beyonce" is already set to become the biggest debuting album by a female artist since Taylor Swift sold an astounding 1.2 million copies of "Red" in the week corresponding to Billboard 200 chart dated Nov 10, 2012. And if predictions in the 600,000 range hold, the set would grant Beyonce the best debut week- and best sales week period- of her career. Her 2006 album "B'day" started with 541,000 in September 2006.
