I agree with those that believe a subscription model is harmless. While it may still impose DRM, you're under a clearer understanding that by subscribing you have certain limitations imposed upon the music you listen to, such as no CD burning and then the usual account authorization for current protected tracks. The biggest hurdle I can imagine in all of this is the studios' cooperation with this business model. If too many songs are out of reach of subscribers it would be a huge negative. This is also a problem with the Zune Marketplace, in which many albums are not available for the "all you can eat" model, and some are not even allowed to transfer wirelessly. I believe that to make this truly work, the entire iTunes library will have to be on board. Not a single album should be out of reach for people who paid good money to access the entire library.
