This seems like it has too many cons...I can just see that allegations of chart trickery from major artists. If Billboard's objective is to report on the most popular music during any given week, then maybe there needs to be a separate chart for just that. If the goal is to report on the most purchased music in a given week (coins exchanged for a product), then there should be a chart for that sole purpose. There are already 1,000 billboard charts, there's no reason this couldn't be an option. The reality is that the flavor of the month artists will be top 10 on the popular charts, but some less popular artist with a loyal fan-base will be the bigger, sustained seller.
