Let me try this one more time. And let me try to actually label two things differently.
I just bought a new iMac in December. Technically, "iTunes" as an entity does not exist any longer. iTunes used to be the catch all for their music sales, plus the way they sold TV shows, films, etc.
As you may have noticed before, earlier......they broke the TV and movie parts off into their own apps. Movies have their own icon/app now. TV shows are now purchased or viewed in the Apple TV app or on AppleTV itself.
The iTunes icon on my desktop was replaced by an icon that, if I hover above it with my cursor, says "Music." In almost every single way, this acts E X A C T L Y as iTunes did. Same access to my library of songs I purchased AND ripped. There's an option in that same menu on the left of the screen (where my playlists are) to click on the Music Store, which is the same thing as iTunes Store - if you want to purchase songs from Apple. I also still occasionally purchase mp3's from Amazon (cheaper there sometimes) and they still load into Apple in exactly the same way.
So let's call that Music. It's the Music App and the Music Store.
There is a difference between Music, the app and platform, and Apple Music the streaming service.
You DO NOT
DO NOT

DO NOT
DO NOT
have to use or engage with Apple Music the streaming service in any way shape or form ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever, ever.
It is simply another choice you have IF you want a more Spotify/Pandora experience. But it's like a button on a remote control. It is one of multiple options and if you never press that button, you never have to use it.
For Apple, they are putting this all under the umbrella NAME of Apple Music. But you can think of Apple Music as an onramp to a highway. Many people will get on the onramp and go to the right, where the streaming stuff is. but you can go to the left, where all the local stuff is, all your purchased and ripped items.
When/if Apple says "have three months of Apple Music on us for free" they are talking about their *streaming service.* You will ALWAYS have access to your music on Apple Music, the app, the technical platform, for free, as it is part of the mechanics of having a Mac. With a few minor exceptions (breaking TV and film off into their own apps/icons, deleting the free Internet radio links), that part of Apple Music acts the same as iTunes.
This link may help you understand. (Fuck knows I don't know how it can be any clearer.) See the bits about "can I still play my mp3s" and "do I have to pay for it" etc.
