This is, in fact, the same version of iTunes Match that iTunes
users could pay for as a separate subscription since Apple began
offering it years ago. I am one of those users. However, all
subscribers to Apple Music will get the new version of iTunes
Match at no extra cost. This update also means that all Matched
songs will download DRM-free.
If you are a current iTunes Match subscriber and subscribe to
Apple Music, you can let your Match subscription lapse when it
comes up for renewal and still receive the same benefits. If you
don’t subscribe to Apple Music and still want the benefits of
iTunes Match, hold on to your subscription.
I’m sure there are reasons for the way things are, but from the outside, combining iTunes Match and Apple Music should have been there from day one. It would have made transitioning so much easier and more compelling.
