Art valuation has never been fair. It's all zeitgeist and marketing. Spotify or not, it will always be that way.

This however comes down to a matter of scarcity right? How many pop stars have feet on onlyfans vs songs on Spotify?

I've been a Spotify user for a few years now. It's a discovery platform for me. It drives vinyl, merch, and live sales. If you enjoy an artist go see them live and buy their merch.
