I don't think Spotify should be celebrated. For a start, Spotify exists because the music companies basically lost against piracy, but it was their own fault. That devalued recorded music to such an extent they had to change that business model. They collect a paltry amount from streaming (the artists get even less), but it's all they can get now. They've changed their model entirely. Bands are gone. Generic, marketable solo artists are in and money is made from concerts. Records are just marketing.
Secondly, though, Spotify is just as bad if you are into proper records rather than concert marketing. Want to listen to Queen? Well, I hope you like the god awful remasters, because that's all that is available on Spotify. And whatever is available right now could change at any moment. It's not a music collection.
The only way the record companies could have kept selling records is with vinyl. But they killed that to get more profits decades ago. Good luck convincing people music is worth sitting down for like people do with books, movies and games. Yeah, let me sit down and listen to Cardi B for the next 40 minutes, said no one. The youth just press play on a playlist and whatever comes out doesn't matter, it's all basically the same anyway.
