This sounds a bit like the cinema thing to me. You buy a card that allows you to watch the movie, but only once. You can't take it home with you and watch it as much as you want. Same for that od2 service.
PPV still allows me to tape the program to VHS or DVD quite easily. For recording that "downloaded" music you would have to set up an audio software like Soundforge or CoolEdit to record it. Quite annoying. :?
Guess that's the idea behind that service. 8 out of 10 users don't know how to properly set up their software to record those tracks, so illegal downloads get less.
