On its first week out, MDNA sold an entirely respectable 359,000 copies and earned Madonna her eighth career No. 1 album. But things are apparently not so rosy for week two — as in, MDNA may suffer the biggest second-week-sales drop-off in history. Early projections put the album at 46,000 for week two (Hits Daily Double, which updates throughout Monday and Tuesday, is currently reporting 34,936, which seems to back up the low estimate); Forbes suggests that MDNA's big first-week numbers were thanks to a concert promotion that included CDs along with ticket sales. And in case you were concerned that maybe some computer glitch scrambled all the numbers, Adele is still projected to sell 100K-plus this week. Breakups > drugs, apparently.
