I think it's better to have separate charts, it will be much more precise than any combined chart that will have to be weighted by the company presenting it. I don't understand people complaining about oricon not including digital sales when they have other charts for that readily available. It's not oricon's fault that so many people turn to them for info. In that respect I think billboard is pretty worthless, however like sunshine slayer said it's always better to have more sources to choose from.
