Part of me wonders if this can possibly lead to getting Apple Music or Tidal's weekly numbers published on their own as more and more groups begin to publish charts with them.

Even knowing the average number of streams the usual Top 10 on AM and Tidal get can help in assessing and contextualizing their size in the market versus Spotify.

Very nice!!!!

Song - Nielsen streaming - HDD+YT

Closer - 38.9m - 38.3m
Heathens - 21.0m - 20.6m
Cold Water - 19.9m - 19.2m
Let Me Love You - 14.6m - 14.0m
Broccoli - 17.3m - 18.0 (how?)
My Way - 6.0m - 6.9m (how?)

It looks like we have now very accurate source of streaming numbers. But still I don't get why sometimes HDD+YT has higher numbers than nielsen.
