Just one more week and Adele will be 21 for ’21′! The Pop/Soul singer’s album has now spent 20 weeks at #1 on the United World Chart, extending her lead as 2011′s best-selling artist.

’21′ sold over 212k in the last 7 days, bringing its grand told to 8.65 million copies in just 7 months. One spot behind Adele is her British counterpart Amy Winehouse whose ‘Back To Black’ moved 165k copies, representing an 8% sales dip compared to the previous sales period, while Lady GaGa’s ‘Born This Way’ finally passed the 4 million mark by selling 106k at #4.

Unsurprisingly, Kelly Rowland’s ‘Here I Am’ experienced one of the larget sales decreases of the week. The record fell an astounding 23 spots to #30 after selling only 27k units, proving that her name certainly isn’t strong enough to sell albums on its own.

Sales were just as impressive on the United World Track Chart as LMFAO’s ‘Party Rock Anthem (Ft. Lauren Bennett & Goon Rock)’ sold over 346k at #1. Check out the the lineup of the leading Urban/Pop albums and tracks in the world below:
