@nova The credits for Just Dance and Dare have been fixed.

As for how the covers work, I only usually have one or a few for each song to pick from. I can't use whichever I want as you see:

@pachylad Both added! Thanks for the previous ones as well.

The reason I didn't add "A Holly Jolly Christmas" previously is that it was affected by a bug which merged its total with several other tracks. It seems now that the only track it's merged with still is his own "Christmas Child". This one likely inflates it by a negligible amount still so I'll add it (for now).

Stumblin In by CYRIL isn't on the list. 598,848,222 streams.

@al i had sent that post in the comment section for the newly-merged most streamed songs page.
