In the same week that she celebrates 52 weeks on the Billboard 200 albums chart, all of them spent in the top 10, the singer set yet another high-water mark when she notched the biggest sales week yet following her Grammy Awards comeback . In the wake of her six-for-six night at the awards show, Adele rolled up her biggest sales week to date, moving 730,000 copies, more than doubling her previous high mark of 399,000 for the week ending December 25, 2011, according to figures provided by Nielsen SoundScan. The last album to sell more copies in a single week before Adele’s big jump was Lil Wayne , whose Tha Carter IV moved 964,000 in August 2011. To put her giant leap into perspective, in her 52nd week on the charts, Adele moved the third-highest amount of product of any artist in the past year, surpassed only by Lady Gaga ‘s Born This Way (1.1 million) and Weezy, and coming in ahead of highly anticipated chart bows by Drake (631,000), Coldplay (447,000), Jay-Z and Kanye West (436,000), Lady Antebellum (347,000), Beyonc
