I certainly wouldn't be interested in any program that requires a subscription or my media stops working.
I, like many others here, am pretty well opposed to DRM in general. I feel it violates our constitutionally "guaranteed" Fair-Use rights and finally allows the media conglomerates to do through technology what they have been unable to do in the past via lawsuits.

It's my strongly held belief that copyright law is severly broken in many ways, but perhaps the worst is the anti-circumvention clause of the DMCA. This effectively grants the media conglomerates perpetual copyright. The copyright law says that the copyright persists only for a limited period of time after which it is supposed to pass into the public domain (of course, they'll just keep pleading for extensions because Steamboat Willy might *gasp* pass into the public domain). That is how society and knowledge progresses. If you look back over the history of music and literature, it is riddled with borrowing (and sometimes outright stealing) from those who came before, changed and updated and modified into new forms.
That is how we have progress in the arts.
The problem is that with DRM, no one can force the companies to give up their copyrights even after the now-rediculous period of time expires before it passes into the public domain, because circumventing the technology is illegal! How then, will the musician of the future be able to remix and reuse the content of yesterday in order to create something new and better? Worse even, we could lose the legacy of the music that came before. So much material out there is already unavailable because it has gone "out of print". But at least once the copyright expires, the people who do have the rare copies are free to distribute it to the world so that it can continue to be enjoyed. With the DRM-enabled media of the future, this won't be possible. Once the music is gone, and the DRM no longer works (because the company selling it no longer exists or because the technology has moved on without that format), it will be gone forever.
The really sad thing is that all this DRM stuff is being pushed down our throats under the guise that it will "protect the poor, starving artists" from the "evil pirates". In reality, it just allows the entertainment "industry" to double and triple charge you for content you already own. The DRM isn't ever going to stop piracy, the same way Windows Activation didn't stop people from pirating windows. All it does is stop the average, clueless consumer from "format shifting". Want to watch that show on your new HDTV? Pay up. Want to be able to then watch the show you already paid for on your new, shiny iPod? Too bad, you can't convert it because of the DRM... Pay up. Want to listen to the music from your home computer on your work computer? Nope, you'll need to buy it again. Want losseless versions of that music you just bought on iTunes/Napster/Yahoo/Google Video/JRiver? Cha-ching!
All the while the pirates in China are churning out more "illegal" copies than ever before. They basically just figured out a way to criminalize format/time-shifting, which they've really wanted to monetize all along. Plus, it guarantees that the "corporation" will always have a place in the entertainment business. The internet is the media company's worst nightmare... Think about it. Radiohead doesn't really need the record label in an all-digital, internet-connected world. They could just record at home on their uber-powerful computers and release it on a web site (distributing it via Bittorrent so they don't even have to pay for bandwidth). With DRM though, Radiohead still needs the label. They have the DRM technology patents, you see, without which (sound the alarms) the pirates will attack. (But the pirates still attack you say? Get out of here, we don't need your kind around here).
I think Pink Floyd said it best...
Grab that cash with both hands and make a stash.
New car, caviar, four star daydream,
Think I’ll buy me a football team.

The only "product" of this type I'd ever buy into would be one that guarantees my Fair Use rights to format and time shift at will, guarantees my First Sale rights (I have to be able to re-sell my media to others for a price that only I determine), and one that doesn't "expire" if I stop paying some subscription fee (or if the company running the service goes belly up).
Period.
