TLDR?

The standard payment to an artist on Spotify is “$0.003 to $0.005 per stream”: https://simplebeen.com/artists-make-on-spotify/

That is basically nothing for any artist that isn’t in the top tier of mainstream success.

prior to Spotify coming along the industry was in decline as downloading MP3’s on torrents and file sharing programs was the norm

You’re essentially pirating music by using Spotify, you are not paying the artists that you listen to in any meaningful way.

I’m still getting a ridiculous amount of value from Spotify

If only the same could be said for the artists you’re listening to…

That seems extremely high, can you explain your listening habits? Are you listening to all of those albums start to finish? Are you selecting each of those albums or just letting the algorithm run wild?

You’ll formalise your knowledge in college, for now just work on whatever you enjoy most without worrying too much about what its teaching you.
