I didn’t even know about this but I think you’re right. I just scrolled through the Calm Piano playlist and the third song down was by an artist with millions of streams, but absolutely zero online presence outside of Spotify and Apple Music. Their about section was just a generic sentence.
I hate this. So the idea is that the cost of creating this music is less than the payout of streaming royalties if they push the songs on their official generic playlists, effectively keeping the money in-house rather than paying to an external artist…
