So “Fairplay Version 3” apparently has the ability to handle expiring content. If I had to hazard a guess, I’d say that Apple could, if they wanted, apply the same expiration logic to music. Steve Jobs has repeatedly stated that customers don’t like to rent their music, and the relative success of online music sellers (e.g. iTunes, Amazon, eMusic) as opposed to renters (Rhapsody, etc.) would seem to bear that out.
Still, it’s an interesting new wrinkle.
There is a 20% chance of tomorrow.
