The Billboard chart in question is behind a paywall.

Someone on a Reddit discussion on the same song pointed out that it could be bypassed with:

open.bolha.tools and plugging in the Billboard URL www.billboard.com/…/country-digital-song-sales/

That being said, while I can see the chart, I don’t see any numbers, so I’m assuming that they must be coming from somewhere else, though I don’t have any reason to doubt that; it sounds like tasteofcountry.com is reputable.

That article does point out that there are a substantial number of Spotify users listening to the song, though if I remember, there was some past discussion about how various people had tried trying to game Spotify’s recommendation system to try to get more people listening to their songs, so maybe someone could just be leveraging that hard?
