The Billboard charts are determined by a number of factors, from physical sales to streaming numbers. However, when it comes to the weekly format, its been pretty consistent.

Since 2015, Billboard counts each week’s sales from Friday to the following Thursday. Although that is pretty clear cut, it’s not for Chris Brown.

He took to Instagram on Thursday (Nov. 2) to express his frustration about his new album, Heartbreak on a Full Moon, only getting three days of sales to count for its debut week on the chart.

“DONT UNDERSTAND how that is,” Brown wrote.

How did that happen? Well, instead of dropping the album on Friday (the day albums usually drop), Chris opted to drop the project on Halloween (a Tuesday). So, he only gets three days (Tuesday, Wednesday and Thursday) to determine his position on the charts.

Adding to Brown’s confusion is recent platinum certifications he received. He said he got nine platinum plaques from RIAA over the past year, which he said “dropped out of the sky.” While this should point to him gettingdiamond certification, there’s a reason why.

Brown was actually issued nine platinum certifications this year for solo singles (and two more for featured appearances). The rare diamond certification is for 10 million sales or album equivalent units of either a single or an album. So, getting 10 separate platinum singles does not count as a diamond album.
