Just wanted to share this: In the latest iOS 8.4 Beta, you can see bits of Music already. All you have to do is go to an album and scroll down until you see recommendations for music. Once you tap those, you'll get informed that you need a subscription. On the next screen, you can choose one then (in the future). Interestingly, Music seems to cover the functions of iTunes Match as well. In the settings, iTunes Match is now labeled "iCloud Music".
