Check out the "The Dark Side of Spotify" video on youtube, very enlightening.
Spotify is paying lower than most the other streaming platforms as well. Some of the others are subscription only though.
Being a 'musician' or 'artist' has become just a side hustle because you need something else to make your music heard enough to make a livable wage from it. Become a Meme Youtuber and funnel your fanbase to music to monetize them further.
If you want to survive off just being an 'artist' then you need to make music to a fanbase that listens.
Music is a background activity mostly. We all mostly love it, we feel like we support it but its just not engaging. It needs a meme video or something for social media to engage with it and get it in front of more people who will enjoy it. In general, A Spotify link doesn't get updoots.
