Maybe 4 isn’t her lucky number after all. Following its #1 debut on the Unite World Chart last week, Beyonce’s ’4′ has already lost its grip of the top spot.

The album experienced a 55% dip in sales and slips to the #2 position this week behind Japanese boy band Arashi’s ‘Beautiful World’ which sold 631k copies. ’4′ sold 232k in the last 7 days, bringing its total to 743k.

LMFAO remains atop the track chart with ‘Party Rock Anthem (Ft. Lauren Bennett & Goon Rock)’ which sold another 371k. The single outshined for chart ruler Pitbull’s ‘Give Me Everything (Ft. Ne-You, Afrojack & Nayer)’ which sold 353k copies.
