Spotify for ebooks? Aren’t the publishers already making enough money?

I’ve heard people opine for a Spotify for ebooks. This isn’t as kooky as when they opine for Netflix or Blockbuster for physical books. The thing is… Spotify is pretty good for consumers, but sucks for creators. Well… it’s not all rosy as some people want to believe. (I really don’t get why so many librarians absolutely loathe the publishing industry, but give the music industry a pass.)
