I already owned the music so it won't change anything for me but this is just further validation of streaming and subscriptions being the future of music. It will be the winning business model and is here to stay.
I'm very happy that Spotify and Amazon Prime have evergrowing music collections. That doesn't stop me from buying new albums (the biggest fear of the record industry).
Same here, I want to own the music I love (and own a huge library) but subscribe to streaming services to discover music and for music I don't like enough to buy.
