Choose a music streaming chart

Since Billboard's China V Chart has been suspiciously unchanging, KKBox is Taiwanese based, and QQ Music limits access, each chart seems to have limitations. So which chart should be used?

Weibo's Fresh Asia Music is a new find and seems to be complete, but who can be certain.

Notes:
* Billboard China is under consideration, not the V Chart
* Some charts exclude OST's, promotional singles, etc.
