Does anyone know if the "% sales reported" is tallied in some particular order? I'm wondering if the way that HITS gets it's sales counts over the 2-day reporting period matches up with the way sales were going, in chronological order, over the 7 days of the previous week?
IF THIS is the way the sales are reported, then maybe it makes sense that U2 is not in the Top 50 yet. From Monday through Wednesday, U2 was not getting any Grammy hype. Many of the other artists, especially Kanye and Mariah, were already getting a lot of hype. U2's hype, even if people stayed up so late to see the results, started on Thursday...about at 50% of the selling period.
One other concern for this week is that the hype from the Grammies would have likely lead to a lot of weekend purchases, but nearly 50% of the U.S. population ended up focusing on a blizzard by Friday, and then it actually hit and lasted all weekend. The other artists dealt with it, too, so who knows. It is true that historical sales boosts showed up when there had been one full week of sales after the awards show. We'll know soon enough.
