Talk:List of Oricon number-one singles of 2018

Adding combined singles
I am just wondering that from December 24, can we just add the combined singles instead, which relies on physical sales, and also on digital downloads and streams. Other countries also used this format in recent years on Wikipedia, Despite this, the combined singles chart archive ends at May 8, 2020 in its website as of this message, and Oricon has a service where you have to pay to see the older results.
