Adele's '21' Tops Charts For 20th Week, Sales Increase 95 Percent

Rumor has it (ding!) that the buzz around Adele's Grammy-winning album, 21, is far from over.

The singer topped Billboard's album charts for the 20th non-consecutive week and sold over 237,000 copies, marking a 95 percent increase.

Another fantastic week on the charts had everything to do with the excitement around Adele's comeback Grammy performance and nominations -- album sales are tracked through Sunday night, so the effect of her 6 wins remains to be seen -- but Adele is the first to attribute her success to her ex-boyfriend, who inspired 21.

"[The album is based on] something everyone's been through -- a rubbish relationship," she said in her acceptance speech upon winning Best Album.

Adele isn't the only singer who saw a spike in sales this week; Whitney Houston's album Whitney: The Greatest Hits came in at No. 6 after her tragic death on Saturday night, even after Sony raised the price of two of her albums in the U.K.
