The product referred to as "Apple Music" isn't library focused. The app now known as Music and the service known as "iTunes Match" is. Apple Music is the music as a service subscription that keeps pushing adverts in app and keeps turning itself back on even if you're not subscribed and have turned it off.
For a while there was a subtle difference in that music uploaded to Apple Music would have DRM applied to it, and iTunes Match would not, but this is no longer the case.
