I believe you are confusing between two separate issues (which do often intertwine): DRM and Subscription Music Services.
With DRM, I am completely and totally against it. 100%. In terms of why I "believe... own the music," my point is if I purchased the music I should be able to rip it from CD, transfer to any music player, use it in my home movies, stream to any of my own personal players over the internet (or via cell towers), etc. Most of these things I consider them fair use and I will continue to use the files on my harddrive the way I like. LEGALLY speaking though? You're absolutely correct. Reality wise though? I completely deny and disagree with the legal community (and RIAA).
With Subscription Music Services, although it isn't for me, I believe that the people on this board who are so adamantly against Apple going in this direction aren't "seeing the big picture." They only talk about what is wrong with Subscription Services: you're renting music, when you stop paying you can't listen, etc. etc. What they fail to realize is the flip side of what (maybe) is possible legally with Subscription Music services: sharing music with friends/family/etc. (as long as they have a subscription).
Examples:
1. No need to "buy" all the songs for iMixes for subscribers
2. Posting playable playlists on websites
3. When you "tell a friend" in iTunes about an amazing song, they can immediately listen to the whole song and add it to their library.
4. Steam your iTunes account songs anywhere around the world.
Those are just some examples. Now, I haven't talked about the "issues with Subscription Music Services" (ahem DRM), but I was addressing the "poo poo-ers" of Subscription Music. There is a good side that many of them simply aren't addressing and/or seeing.
