This floods the market with many, many independent musicians trying to get heard. And the only way to get heard today is to make it onto curated Spotify playlists, build a following, and hope that someone at a record company somewhere hears you and takes interest. Not only is Spotify a tool for consuming music by the public, it is also the main way that musicians have to promote themselves anymore.
As a musician (who gave up the dream of making this a job long ago), it really sucks. There is infinitely more competition out there now, and when you factor in all the AI crap making it on to Spotify (some of which they are responsible for), it is even worse.
