I know I paid for a DRM track; its just bittersweet that I'd have to pay for the same song again to not have DRM. That nets Apple 0 good/evil points in my book.
You don't have to have it without DRM, and you don't have to pay if you want it to not have DRM. What you're paying less than full price for is a completely different bitstream that happens to be encoded from the same original source. It's not unlike getting a credit toward a CD because you happened to own a tape of the same music, which I think you can agree is a rather novel concept.
