In this case it's not pop music, it's instrumental ambient music and childrens tunes.. Very particular set of playlists, Spotify-owned, that if you get into them you're essentially guaranteed millions of streams (as those playlists have tens of millions of followers that I'm sure just have them on repeat often - guilty here as well..)

Aside from the sketchy issue with faking 750 artist names, apparently the music is good and has good artistic intent within the genre.

According to the article, you can do deals where you trade away part of your royalty for a higher placement on those Spotify-owned playlists, which in his case seems to be the right business choice to make by far.
