Why not have the best of both worlds? All you can eat music downloads for a low monthly cost, but DRM free. It doesn't exist in a necessarily easy to consume product right now, but it does exist. I could imagine using something like the Zune Pass plus Tunebite giving you this exploiting the "analog hole". Tunebite plays the music files from a virtual audio output and records it in a virtual audio input. Similar to taping songs off the radio, or playing a CD and recording it to tape. The file would go from a protected WMA to an unprotected MP3 (or ogg, or flac, etc), and all you're doing is playing your legal copy of the song.

That way you can burn it to a CD to listen to in your car or put it on your iPod Nano to take to the gym with you, and the file can't be revoked just because Microsoft changed the license. These are completely legitimate use cases. I'm sure such a hypothetical situation would work with Rhapsody or other music subscription services. Various services may embed a code in the file to tie it back to you if it winds up on a sharing site. I don't know if this method would remove that, so I would suggest keeping these files purely for your own benefit.

What happens when you stop paying the monthly fee? I suspect the people offering this service will want some assurance their customer base will not disappear after downloading every song ever made in the first month.

By default, if you stop paying you lose all your songs. In my hypothetical situation, you would keep them. Zune Pass does give you 10 downloads each months DRM free that you can keep forever, so I guess you could claim it's moral if you don't run more than that amount through Tunebite overall.

I was just throwing it out there as a hypothetical situation where someone could have a subscription service and also be able to use their songs as they want to use them. I subscribe to the Zune Pass and I know I have this capability, but I've never actually felt the need to exercise that power.
