I will summarize again: the Digital Track Sales and Streaming are the reasons for the decay of the global album sales, and that's why we follow the example of the US-Billboard Chart and other... from the week 2, 2015 on, we'll integrate Track Sales and Streaming to the Global Album Chart.
It was a very difficult decision, but believe it or not, a pure sales-based album chart has no future! The additional sales from Digital Tracks and Streaming bringing a fair compensation and incidentally more stability!
Couldn't be farther from the truth. I feel uncomfortable about all the change but it's necessary. Sales are dying and the charts are, for once, ahead of the curve on this one.
