Here's how:
1. You can't find it on Spotify, Apple, Google.
2. That's because - aside from Youtube - it's Amazon exclusive.
and...
So a *new* song included in lots of Amazon playlists becomes by default #1.
Ie: Voice search, licensing deals, manual curation, and algorithms have crowned Ellie Goulding's "River" the last #1 of the 2010s.
This is the song. Either about the baby Joni Mitchell put up for adoption, or about Graham Nash, depending on who you believe.
