Spotify chill-hop/"music to study to" playlists are popular and people listen to them repeatedly and for long stretches of time which makes them lucrative for streaming revenue. I know someone who runs a chill-hop "record label". Their most popular songs get on big spotify chill-hop playlists and have ~10 million spotify streams. This equates to around $50-70k USD. Most of their releases have a fraction of this but it is worth it for the odd hit.
