I get what you are saying. Now forgive me if I'm wrong, because I don't subscribe to match.
They advertise that iCloud is what keeps your music in the cloud... they don't say that you need a match subscription to take advantage of getting your music in the cloud, Match is a service to get non iTunes content to the same place!
Ok, I just did a bit more searching on apples site. It looks like if you want the music to appear in your library rather than just in the store, you do have to pay for match, so i guess match does add more features than just the ability to get non iTunes to the cloud.
Let me illustrate it for you with an example. Let's suppose that I was that 1 person in 100 million who actually has a very large library of music, every last song purchased at the iTunes store. My library is 25 gigabytes in size, yet I only have a 16GB iPhone. Normally I'd have to choose some subset of music to keep on my phone using the limited room I have. Yes, at any time, I can go and re-download that song I'd like to hear but don't have by going to the Store and browsing for it, and waiting for it to download. However, now if I subscribe to Match, no, I don't have any songs that technically need to be matched, but now I can wipe my phone clear of all the music I normally had to sync to it, yet my Music app still shows me my
entire library. I can play any song I want in an instant. I can make a playlist, I can shuffle the entire thing - even though I don't have any songs physically on my device. Nor do I have to wait for it to download before hearing it. Better yet, at work, I can turn on Match on iTunes on that computer, and I get my entire library there for streaming - with all of my metadata in sync!
This is where the confusion is.
They call it Match - but it's really their streaming music/keep everything in sync service. Match is just there to make it all work.
