The 20/20 Experience is completing its fourth week of life, having already spent its initial three on top of the charts - the first since Taylor Swift’s Red from late last year. Since figures were collected last weekend, Justin Timberlake’s long awaited album hovers comfortably around 2 million in sales. Maybe more. In its first week, 968,000 copies were sold in the US alone (516,000 of them CDs), with iTunes clocking around 580,000 worldwide sales, making it the fastest-selling album to date on Apple’s iTunes Store. In an era where the digital piracy is the norm, that’s no easy feat.
