I mean the streamers have to get paid too, you might hear artists complain about how much money Spotify takes but as someone who has released lots of music on Spotify they do pay you, pretty decently too! Lots of artists are making hundreds of thousands a year from just Spotify and the business itself is profitable, which allows pretty much anyone to upload their music and try their dream.

That is valuable in it of itself, without services like Spotify many of the artists I listen too would probably have given up on music for a boring IT job, like I did.
