Million reasons has .105 and Perfect Illusion has .307. Does that mean MR has sold 1/3 the amount PI as on itunes?
those are the sum of the Points a song get day by day. and the Points are calculated from which positions the songs have by the time kworb updates his Itunes WW chart, with more Points from bigger markets etc. itīs a very sketchy chart tbh, songs that doesnīt even chart in US top 400 can be higher than a song that is #1 in US, if it charts in more other countries that barely even have sales.
